Nick Bosa is "pretty confident" he'll receive a contract extension from the San Francisco 49ers by training camp.

Bosa is entering the final year of his rookie deal after the Niners picked up his fifth-year option last offseason.

"It's pretty high," Bosa said when what his confidence level was about getting a deal done. "Yeah, I think I'm pretty confident about that."

Kyle Shanahan was asked if the he's talked to Trey Lance or Lance's agent about a potential trade from the San Francisco 49ers if Brock Purdy is healthy by Week 1.

"No," said Shanahan.

The Minnesota Vikings had talks with the 49ers about Lance at the combine. The 49ers also fielded calls from other teams.

John Lynch says that Trey Lance has done well during the San Francisco 49ers' offseason program.

"We're extremely high on Trey," Lynch said. "The great thing for Trey and for Sam Darnold, that we brought in, is with Brock [Purdy] off to the sideline — Brock had his first session throwing the other day, and everything’s tracking great — but those guys have got the work in the offseason, and they're both relishing that opportunity.

"Really proud of Trey. Trey came back off a broken and dislocated ankle, and he's out there, has had a really, really quality offseason. So we still remain very high on Trey."
