Willis was active in seven regular-season games for San Francisco in 2025, playing 98 snaps on special teams and 13 on offense. The 26-year-old will likely be a depth option for the 49ers' playoff matchup against the Seahawks, behind Luke Farrell and Jake Tonges as they take over for George Kittle (Achilles)
