The injury happened when Drummond went up for a rebound and came down wrong on his right foot, rolling his ankle.
The big man immediately dropped to the floor, clutching his right foot in obvious pain as Arnie Kander came sprinting to his aid. Drummond was tended to on the bench for the remainder of the game, in discomfort, but tried to walk off the court under his own power after the final horn. Unfortunately, he only made it a few steps before keeling over in pain. Drummond was then helped to the locker room by Kander and Greg Monroe.
Shortly after the game, Keith Langlois tweeted that Drummond's injury is a sprained ankle and is considered day to day. With two games left on the schedule over the next five days, it doesn't make a whole lot of sense to bring Drummond back this season.
