Rookie forward Jordan Bell left the game after spraining his left ankle 24 seconds after tipoff between the Warriors and Bulls on Wednesday night in Chicago.
The sprain was discovered when Bell underwent an X-ray at the United Center. He will undergo an MRI test on Thursday to determine the full extent of the injury.
After leaping in an unsuccessful attempt to block a dunk by Bulls center Robin Lopez, Bell landed awkwardly on his left leg and remained down for several minutes before he was placed in a wheelchair and escorted into the locker room.

After the game, Bell addressed the injury with the media in Chicago.
"Landed really awkward. Felt some kind of a sharp pain in my ankle. When I fell, I tried to touch it to see if anything popped out. I didn't feel anything, so I thought about getting up but then the pain hit me again, so I just laid there," Bell said.
Initially, Bell thought he had broken his ankle.
"I thought it was at first, that's what it felt, but luckily, X-rays were all good," Bell said.
