The San Francisco 49ers have decided to name Sam Darnold the backup quarterback to Brock Purdy, which leaves the future of Trey Lance in limbo.

The 49ers selected Lance with the third overall pick in the 2021 NFL draft. After backing up Jimmy Garoppolo as a rookie, Lance won the starting job last season. But Lance suffered a broken right ankle in Week 2 and missed the rest of the season.

John Lynch said before the NFL draft in April that he'd received interest from other teams about a possible trade for Lance. At the time, Lynch said it would take something "substantial" to part ways with Lance.

"Yeah, I think there's a lot of smoke really," Lynch said in April. "It hasn't been extremely active and it's not like we've put it out there that, 'Hey, we're taking offers for Trey.' That's not been the process. ... It hasn't been that substantive."

On Tuesday, Shanahan noted the improvements he has seen from Lance.

"This offseason was just kind of getting healthy again and redefining how he throws, getting his balance," Shanahan said. "I think Trey from when he got hurt to where he is now, I think it helped him."
