Rose suffered a sprained left wrist when he collided with Howard with 55 seconds left in the first quarter of Thursday's contest. He stayed in for the rest of the quarter before leaving the floor.
An X-ray initially revealed the sprain. Bulls coach Vinny Del Negro said after a 111-82 loss to the Magic that the All-Star guard would have an MRI done on the wrist on Friday. Del Negro was unsure if Rose would play against the Miami Heat.
"Derrick has a sprained wrist," Del Negro said. "I have no idea how bad it is. He's going to get an MRI [Friday] to see how bad the damage is and see how he feels."
Rose's injury comes on the heels of center Joakim Noah's absence due to plantar faciitis in his left foot. Forward Luol Deng also sat out Thursday because of a strained calf muscle. Center Brad Miller has a thumb injury and rookie guard Taj Gibson plantar faciitis in both feet, though both started.
"We're a different team than we were," Del Negro said. "From our injuries, to the trades, to everything involved. We're without a lot of our guys. There's no excuses. It is what it is. We've got to find a way to get healthy and weather the storm like I talked about, but there's no question we are a battered bunch right now."
On Feb. 10, Howard fouled Rose in Chicago just two minutes into the game and Rose was diagnosed with a hip bruise. Speaking after Thursday's game, Howard said he didn't remember much about Rose's injury, just that Rose went up and fell.
Howard also said that he didn't think Thursday's injury was a case of deja vu, noting that he and Rose were on good terms.
"As a big man, you never try to hurt anybody when they come down the lane," Howard said. "Me and Derrick are cool. I think he's a great player. A great person. Never wanted to see him get hurt. But I always tell him, if you come down the lane, always come off two feet. That way you'll be on balance. You come off one all it takes is for somebody's body to hit you and you're going to fall. I hope he gets better. I hope there's nothing seriously wrong with him. But I never intended on hurting him. It's just the way it happened."
