A magnetic resonance imaging test (MRI) taken on Friday revealed that Kirk Hinrich suffered a significant strain to his right hamstring with 3:07 remaining in last night’s series-clinching game six win over Orlando, according to head athletic trainer Wally Blase.

Hinrich is listed as doubtful for the Eastern Conference Semifinals series vs. Chicago, which begins on Monday.

Gilbert Arenas definitely will play when the Orlando Magic host the Atlanta Hawks in Game 5 Tuesday night at Amway Center.

"I'm not stupid!" Stan Van Gundy said after the Magic completed practice today.

"Yeah, he's going to get his opportunity again tomorrow. There's no question. I think that he played great. I've tried to say this in his defense all year: If you look, last night with J-Rich out, he knew he would get more extended minutes. So I think he plays more — I'm not going to say 'relaxed' — but more confidently that he doesn't have to worry that it's going to be a four- or five-minute stint.

"I'm not going to sit him out tomorrow after what he did. We'll see how it goes. We'll see what adjustments they make to his pick-and-rolls."

Atlanta Hawks coach Larry Drew said the Magic have gotten away with some illegal screens.

“I know that the way they play is to fight through screens and there’s going to be some contact,” Drew said. “I don’t know, maybe what’s been said, maybe that evens up all the illegal screens that’s been set. We feel that they have allowed to play a certain way.

“Our big guys are put into a position where they have to set screens, and I want them setting screens. If they try to fight through it, I want them to hold their crowd, but if they go through it, it’s a foul. I don’t see any real flopping going on.”

Magic coach Stan Van Gundy said he’s fine with the physical play between his team and the Atlanta Hawks, but he’s frustrated by what he calls the Hawks “flopping” in an attempt to draw fouls.

“I like it when guys stand up and fight like men,” Van Gundy said Saturday. “I think that is what the game is all about. The one thing that frustrates me is all the flopping.”

Van Gundy cited three plays from the Hawks’ 88-84 victory in Game 3 on Friday.

Hawks center Jason Collins drew a charging call when he hit the court after contact with Orlando center Dwight Howard and later did the same to guard Jameer Nelson. Van Gundy said Howard “touched [Hawks center] Zaza Pachulia in the chest on a screen and that sent him to the floor.”

“The one thing I learned is our guys are a lot stronger than I thought they were,” Van Gundy said sarcastically.

The Atlanta Hawks’ Zaza Pachulia has been suspended one game without pay for headbutting Jason Richardson and fighting. Richardson was suspended one game without pay for shoving Pachulia in the face and fighting. The suspensions were announced today by Stu Jackson, NBA Executive Vice President, Basketball Operations.

Pachulia and Richardson will serve their suspensions on Sunday, April 24 when the Magic are at the Atlanta Hawks for Game 4 of the 2011 NBA Playoffs.

Orlando Magic coach Stan Van Gundy hasn’t made a decision on whether to use Gilbert Arenas as the team's backup point guard.

"I don't know what we're doing," Van Gundy said. "I haven't decided exactly what we're doing. I know Jameer's going to play a lot of minutes. I know we're going to use J.J. [Redick off the bench], I know we're going to use Q[uentin Richardson] and I know we're going to use Ryan [Anderson].

"As far as what we do at the backup point I'm not totally sure."

Arenas shot 1-for-3 in Game 2.

The Knicks and Blazers will look back on the first two games of their first round series with regret over missed opportunities.

• Boston Celtics 96, New York Knicks 93

Carmelo Anthony had 42 points on 30 shots, playing about as well as he is humanly capable, but without Amar’e Stoudemire in the second half and on an 0-for-11 from Bill Walker, the Knicks return home down 0-2.

Rajon Rondo had 30 points, hitting on 10 of his 15 attempts around the bucket. It was Kevin Garnett who came up big in the end with what proved to be the winning bucket in the closing seconds.

While the Celtics still have problems at center and their bench isn’t giving them much, to see Rondo play with the type of aggression he displayed on Tuesday is highly encouraging for their title chances.

• Orlando Magic 88, Atlanta Hawks 82

This was an ugly game offensively all the way around, but Dwight Howard was once again a monster and the Magic were a +18 from the line.

Howard had 33 and 19, going 9-for-12 from the floor and 15-for-19 from the line. If Howard can sustain that type of efficiency from the free throw line, Orlando can get away with the 4-for-16, 4-for-15 and 3-for-12 posted by Hedo Turkoglu, Jameer Nelson and Jason Richardson respectively.

There is a lot that can happen with Dwight Howard over the next 14+ months, but games like this from his supporting cast do not bode well. 

• Dallas Mavericks 101, Portland Trail Blazers 89

While one of the main storylines is appropriately the discontent of Brandon Roy, I’m not sure it really matters how Nate McMillan treats him when Peja Stojakovic and Jason Kidd are combining to shoot 8-for-16 from distance.

Dirk Nowitzki had 33 points on just 22 shots thanks for a 15-for-17 from the line. 

Unfortunately for the Blazers, they largely matched the Mavericks in terms of shooting efficiency, but were a -7 on second chance points and -7 on points off turnovers as well.

The Atlanta Hawks scored most of their points from the perimeter against the Orlando Magic in Game 1.

"We want to make them do something else," Dwight Howard said. "Jamal Crawford shot a lot of jump-shots; we didn't force him to get the ball to the basket and try to finish; same thing with Joe Johnson, with the floaters from far away and jump-shots. We've gotta make those guys do different things."

It's difficult for the Magic to defend the Hawks' jumpers because the Hawks possess a size advantage at all of the backcourt spots. Kirk Hinrich (6-foot-4), Jamal Crawford (6-5) and Johnson (6-7) are all lengthy for guards.

That allows the Hawks to isolate their shooters and allow them to take pull-up jumpers in one-on-one situations, negating the Magic's ordinarily solid team defense.

Only 11 of Atlanta's 19 successful outside jumpers were assisted.

"What we've got to do, I think, is do a better job of taking away their space to get the pull-ups," Magic coach Stan Van Gundy said. "We've gotta get our help to them a little bit earlier and try to keep them out on the perimeter a little bit more."

Jason Collins allowed Dwight Howard to score 46 points in Game 1.

“I try to frustrate him and do what I can to get under his skin,” Collins said.

Based on his conversations with Howard during the game, Collins said he thinks he accomplished his goal. In the second half Howard was called for a foul after he head-butted Collins, though Howard said the blow wasn't intentional.

“He pulled me back,” Howard said. “Of course I am going to fly back. But he should get an Academy Award.”

Collins said he won't change his tactics when he's one-on-one against Howard.

“He doesn't like physical play,” Collins said. “He likes to spin off, get lobs and get dunks. Like most players that like to score, he doesn't like getting hit. So our job is to hit him and be physical with him.”

The New York Knicks will meet the Boston Celtics in the first round of the Eastern Conference Playoffs.

The match-up was clinched Monday night with Philadelphia losing to Orlando and the Celtics losing in Washington. The Heat clinched the second seed on Monday by beating the Hawks in Atlanta.

The playoff match-ups in the East are now complete set and as follows:

- Chicago (1) vs. Indiana (8)
- Miami (2) vs. Philadelphia (7)
