Despite losing Jimmy Garoppolo to injury on Sunday, Kyle Shanahan says he'd be surprised if the San Francisco 49ers added Baker Mayfield this week.

The Carolina Panthers released Baker Mayfield on Monday. For the Niners to acquire Mayfield, he would have to fall to their spot in the waiver wire (No. 24) or clear waivers and sign as a free agent.

Adam Schefter reports that Mayfield is expected to be claimed.

"We look into everything, but that would surprise me right now," Shanahan said of Mayfield. "We've got to discuss more this afternoon and stuff. I've always been a fan of his, but I feel really good about our players. We'll look into everything, but I feel pretty good with where we're at right now."
