Derrick Rose injured his left hamstring late in the Chicago Bulls' win over the Toronto Raptors on Thursday.

Rose will be re-evaluated on Friday and could receive an MRI.

"I guess it's cramps in my hamstrings," Rose said. "But I think it's minor, and they decided to pull me out."

Rose left open the possibility of practicing Friday.

"I don't know, man," Rose said. "Just missing two years, now you're just going to fall for no reason I guess, man. Just trying to work every day, put in consistent work every day. And don't lose any confidence with these setbacks."
