The move gives the 49ers nearly $31 million in salary-cap space, according to OverTheCap.com. Of course, this doesn't factor in the two-year, $10.1 million deal recently agreed upon by cornerback Emmanuel Moseley, as the structure of that contract is not yet known.
Note: Cap space number updated to reflect OverTheCap.com's Saturday-morning numbers, which drop San Francisco by about $1 million.
San Francisco initially signed Richburg to a five-year, $47.5 million contract on March 14, 2018, and he started 15 games in his first season with the team. The center suffered a torn patellar tendon during Week 14 of the 2019 season, landed on injured reserve, and missed the final stretch of the 49ers' Super Bowl run.
Richburg started the 2020 season on the reserve/physically-unable-to-perform list and did not appear in a game. He has had several surgeries since the injury. In addition to undergoing knee surgery, he had shoulder surgery, which was credited for his setback in 2020. Most recently, he underwent hip surgery.
This is the second time the 49ers have restructured Richburg's contract to create salary-cap space. The team did so before in December of 2019.
