Buffalo Bills tight end Dawson Knox was placed on injured reserve prior to Thursday night's home game against the Tampa Bay Buccaneers.
Knox underwent wrist surgery on Tuesday. He will miss at least four games.
Knox initially injured the wrist in a Week 5 loss to the Jacksonville Jaguars.
The 26-year-old has 15 receptions for 102 yards and one touchdown this season.
Tight end Quintin Morris (ankle) also will miss the game, leaving rookie Dalton Kincaid as Buffalo's main tight end.
Knox has 164 receptions for 1,882 yards and 21 touchdowns in 64 career games (54 starts) over five seasons.
Buffalo elevated veteran cornerback Josh Norman and receiver Andy Isabella from the practice squad prior to Thursday's game. Neither player has appeared in a game this season.
Norman, a first-team All-Pro in 2015, has 16 career interceptions in 137 games (110 starts) while playing for four teams (including Buffalo) over the past 11 seasons. Isabella has 33 receptions for 447 yards and three touchdowns in 41 games (three starts) for the Arizona Cardinals (2019-22) and Baltimore Ravens (2022).
Buffalo's inactives for the contest include Morris and linebacker Baylon Spector (hamstring). The others are safety Damar Hamlin, cornerback Kaiir Elam (ankle), guard Germain Ifedi and tackle Alec Anderson.
Star defensive tackle Ed Oliver (toe) is set to play.
Buccaneers quarterback Baker Mayfield (knee) and wide receiver Chris Godwin (neck) have been cleared to play. Both were listed as questionable.
Tampa Bay's inactives include defensive tackle Vita Vea (groin), guard Matt Feiler (knee) and safety Kaevon Merriweather (ankle). The others are defensive lineman Patrick O'Connor, running back Sean Tucker, outside linebacker Markees Watts and tight end David Wells.
