Niners edge Nick Bosa agrees to terms on record 5-year, $170M extension

Nick Bosa's prolonged holdout is over.

The reigning AP NFL Defensive Player of the Year has agreed to a five-year, $170 million extension with the 49ers, NFL Network Insider Ian Rapoport reported on Wednesday. Rapoport added that the contract includes $122.5 million in guarantees and San Francisco will waive all fines Bosa incurred during his holdout.

Bosa is now the highest-paid defensive player in NFL history with an average per year salary of $34 million, besting Aaron Donald's $31.7 million with the Rams.

Niners head coach Kyle Shanahan admitted on Aug. 30 he thought Bosa would be back with the team by the end of the preseason, but it took until a few days prior to San Francisco's regular-season opener against the Steelers for the two sides to finally strike an agreement.

Shanahan told reporters on Wednesday that he is not sure how much Bosa will be able to play during Sunday's game.

"We'll be smart with it and it'll be based on the next 2 1/2 practices," Shanahan said.

But Shanahan left no doubt that Bosa will suit up Week 1, joking that Bosa would "have to have a beer belly and be out of shape" to miss the opener, per NBC Sports Bay Area.

Based on Bosa's production in the last two seasons, the record contract is money well spent. After suffering an ACL tear in Week 2 of the 2020 season, Bosa has been on an absolute tear on the field, racking up 34 sacks, 40 tackles for loss and six forced fumbles over the
