Deebo Samuel was a limited participant in Thursday's practice session with the San Francisco 49ers. Samuel has a left shoulder injury.

"It's awesome," Christian McCaffrey said. "Anytime he's out there, he brings an extra set of juice that it's hard to mimic without him."

Samuel participated as he normally would during the portion of practice open to the media, stretching and later catching passes from Niners quarterback Brock Purdy during receiver and running back drills.

Testing on Samuel's shoulder Sunday and Monday showed he did not have a hairline fracture, which offered hope that he'd be able to play this week if the pain began to subside.
