A source confirmed to CSNChicago.com that Derrick Rose suffered an ankle injury during Sunday's loss at New York.
The Chicago Tribune first reported Rose's injury.
Rose reportedly wore a walking boot Monday, which was an off day for the Bulls, and continued to wear the boot prior to Tuesday morning's shootaround at the Berto Center.
Rose is reportedly a game-time decision for Tuesday evening's rematch with the Knicks at the United Center and was receiving treatment before Tuesday's shootaround.
Rose has missed 22 games this season total and returned to action Sunday after missing 12 consecutive games due to a strained right groin.
