Hockenson had season-ending surgery on his left thumb Thursday, Adam Schefter of ESPN reports.
The first inclination that Hockenson may be dealing with a serious injury was last Thursday, when he was spotted with a heavy wrap on his left hand. He eventually was deemed doubtful for Week 14 action and inactive Sunday in Denver. Upon returning to Detroit earlier this week, coach Dan Campbell relayed hope that Hockenson would be able to play Week 15, but the ensuing procedure will bring his campaign to an abrupt conclusion, with the expectation he'll complete his recovery by the offseason program. Hockenson will end his third season as a pro with 61 catches (on 84 targets) for 583 yards and four touchdowns in 12 appearances. The Lions will turn to Brock Wright and practice squad member Shane Zylstra at tight end down the stretch.
