Tom Brady’s reported interest in the 49ers won’t be reciprocated.

NBC analyst Chris Simms, a college teammate and close friend of 49ers head coach Kyle Shanahan, reported Sunday that the 49ers will not pursue the Patriots’ free-agent-to-be quarterback. Simms said it was his understanding that the 49ers were the top choice of Brady, 42, a San Mateo native whose parents remain in the area. Brady grew up rooting for the 49ers, who would have provided him with a realistic chance to reach his 10th Super Bowl.

“The 49ers are out on Tom Brady,” Simms said in an NBC Sports video. “That is not going to happen. … They will be standing pat with Jimmy Garoppolo as their starting quarterback.”

Both Shanahan and general manager John Lynch have consistently backed Garoppolo this offseason. The quarterback’s strong 2019 campaign ended with a forgettable fourth-quarter performance in a 31-20 loss to the Chiefs in Super Bowl LIV.

Lynch provided the strongest support at last month’s NFL combine when asked about one of the “crazier rumors” that the 49ers might part with Garoppolo to pursue another QB, presumably Brady.

“We’re extremely proud of Jimmy and committed to Jimmy moving forward — he’s our guy,” Lynch said. “That’s the most exciting thing about him is the room for growth. He’s not come close to hitting his ceiling.”

Garoppolo, 28, is far younger than Brady and rebounded well last year, his first full season as a starter, after tearing his ACL in 2018.

Garoppolo was the only QB to rank in the NFL’s top five in passing touchdowns (27), completion percentage (69.1) and yards per attempt (8.4). His completion percentage ranks third in franchise history for a season, and he ranks fourth in passing yards (3,978) and completions (329).

As for Brady, Simms reported he will choose between the Buccaneers and Patriots, the only team he’s played for in his 20-season career.

The Titans, who were expected to have interest in Brady, re-signed quarterback Ryan Tannehill on Sunday to a four-year, $118 million contract with $62 million fully guaranteed.

Free agency is scheduled to start at 1 p.m. PDT on Wednesday. The legal-tampering period, in which teams can begin negotiating with player agents, is set to begin at 9 a.m. Monday. There was discussion of delaying free agency due to the coronavirus pandemic, but the league sent a memo to teams Sunday afternoon letting them know this week’s schedule would remain unchanged.

The 49ers’ first order of business Monday could be placing the franchise tag on defensive lineman Arik Armstead, who had a team-best 10 sacks last season. They have been in contract discussions with Armstead, and Lynch has said they hope to retain him for a “long, long time.”

The projected franchise tag for defensive ends is expected to be more than $17 million. The 49ers have until 8:59 a.m. Monday to apply the tag.
