Source: Bosa, 49ers agree to record five-year, $170M extension

SANTA CLARA — Nick Bosa is back. Bosa, the reigning NFL Defensive Player of the Year, and the 49ers ended their lengthy contract impasse Wednesday with a reported record-breaking contract extension that makes him the highest-paid player in 49ers history. Bosa and the 49ers agreed to a five-year, $170 million contract with $122.5 million in guaranteed money, a source confirmed to NBC Sports Bay Area's Matt Maiocco. ESPN's Adam Schefter first reported the news. The new deal locks up Bosa to the franchise through the 2028 NFL season. The agreement signals the end of the only contract stalemate during San Francisco's seven-year John Lynch-Kyle Shanahan regime. Bosa did not report to Santa Clara for training camp with his teammates on July 25, and his holdout ends after 44 days. Now, the focus shifts on getting Bosa ready for the regular season, which begins for the 49ers on Sunday, Sept. 10, at the Pittsburgh Steelers. Shanahan said earlier this month he had no concerns about Bosa's physical condition and ability to return to the team and make an immediate impact. "I have as much confidence in Nick as any player I've ever been around in terms of how he prepares and everything."...
