History

Historical Context

In August 2012 the NFL and the NFLPA, led by Commissioner Roger Goodell, allowed one injured-reserve player to return after eight weeks, ending season-long sidelining. Later changes—two players in 2017 and eight-game eligibility in 2018—kept the rule pivotal. Nick Bosa’s September 25 2026 calf injury forces the 49ers to use that eight-week IR provision.
