Chicago Bulls point guard Derrick Rose spent Monday in a walking boot after injuring an ankle during Sunday afternoon's game against the New York Knicks and is uncertain for Tuesday night's rematch, a league source told ESPNChicago.com's Nick Friedell.
Rose will be re-evaluated by the Bulls' medical staff before Tuesday morning's shootaround at the Berto Center, the source said. The Chicago Tribune initially reported Rose's situation.
Rose scored 29 points and had eight turnovers in Sunday's loss to the Knicks, missing what would have been winning shots at the buzzer in regulation and overtime, as well as a pair of free throws with 18 seconds left and the Bulls leading by three.
The reigning MVP had missed the previous 12 games because of a groin injury.
"(He was) about what we expected," Bulls coach Tom Thibodeau said after Sunday's game. "Some good, some bad. Handling the ball was a problem. But our whole team ... we didn't take care of the ball so we put them in the open floor."
Rose said he felt fine after the game and was just trying to get his wind back on the floor.
"I felt good," he said. "When I was out there (I was) just getting my groove back. My wind was OK; just playing. It just felt good to be out there."
After missing just one game last season, Rose has missed 22 games because of toe, back and groin injuries this year.
Rose dealt with an ankle injury during last season's playoffs, but didn't miss any games because of it. He is averaging 23 points and 7.9 assists this season.
