Heat forward Quentin Richardson has missed the team's last two games with back spasms.

He isn't sure if he'll be able to return for Wednesday's game against the Magic. Richardson's back first locked up during last Wednesday's game against the Hawks, which scared him.

The forward had season-ending surgery on his back in 2007.

"I was kind of freaked out by that," Richardson said. "It's been progressing every day since, so I feel pretty good about it.

"Whatever I did, when I when I landed right there kind of made it go into a spasm. We've been treating it every day around the clock."

There is no timetable for his return.
