was wheeled off on a stretcher after getting injured in a collision in the fourth quarter of the team's 32-20 loss on Sunday in San Francisco, but it appears he is going to be all right.
Campbell's sister, Keyonne Campbell, tweeted Sunday night that Campbell was “doing OK,” and followed up early Monday morning by saying: "Calais is fine and he'll be back to work soon."
Campbell felt numbness and tingling in his extremities after the collision but did have movement and waved to the crowd as he was taken off the Candlestick Park field. He was taken to a Bay Area hospital to undergo precautionary MRI and CT scans, and the team reported the initial results were positive.
He was released Sunday night, returned to Arizona on team president Michael Bidwill's plane and attended a team meeting at 8 a.m. on Monday morning.
“The feeling was coming back in,” coach Bruce Arians said. “Our prayers are with him.”
While Campbell lay on the field, fans at Candlestick Park started a wave, leading to admonishing comments from several members of the 49ers organization who called the cheer embarrassing.
"To say I'm disappointed some fans did the wave this afternoon while (Campbell) was down is understatement," 49ers CEO Jed York tweeted.
Campbell took to Twitter to say: "I want to give a big thank you for all the support and kind words today. I am feeling good and anxious to return!"
