Lions Lose Tom Kennedy for the Season: Return Specialist Needs Knee Surgery After the Cardinals Win

A 45-21 road win is supposed to be the kind of afternoon a team savors on the flight home. The Detroit Lions earned exactly that on Sunday in Arizona — and still came home with a season-altering loss hiding inside the blowout. Return specialist Tom Kennedy, one of those glue players whose value only becomes obvious the moment he is gone, suffered a significant MCL injury to his right knee that is expected to require surgery and will end his season, NFL Network reported. Detroit heads into its Week 6 bye at 3-2 with a first-place-caliber roster and a brand-new hole in its return game.

How It Happened

The play itself was routine, which is what makes it sting. Early in the second quarter, Kennedy fielded a punt and ran it back 11 yards before Arizona's Simi Fehoko and Dadrion Taylor-Demerson brought him down. The Detroit Free Press described Kennedy's right leg bending awkwardly backward during the tackle; he did not play another snap. Sports Illustrated added that Kennedy initially walked off under his own power, was examined in the medical tent, and was then carted to the locker room and ruled out. Field Level Media pinpointed the moment precisely: the injury came at the end of that 11-yard punt return in the second quarter of the 45-21 win.

At first, the Lions allowed themselves some hope. Head coach Dan Campbell said after the game that Kennedy was likely to miss some time but that the hope was he had avoided a long-term injury, according to NBC Sports. Monday erased the optimism. NFL Network's Mike Garafolo reported that further testing revealed a significant MCL injury expected to require surgery and end Kennedy's season, with Ian Rapoport also on the report — a story carried by Athlon Sports and Heavy. Campbell then confirmed the outcome himself on Monday, per the Detroit Free Press: the injury, he said, "was significant enough where he'll be out for the season." That is the stinker, to borrow the coach's own framing, inside a 24-point win.

The Return Man Detroit Will Actually Miss

Read Kennedy's wide receiver line and you would shrug: no catches this season, a single offensive snap, and 18 catches for 231 yards across 35 career games dating back to 2019, per NBC Sports. That was never the job. The job was field position, and Kennedy was quietly excellent at it. Through five games he had returned six punts for 79 yards — a 13.2-yard average — and nine kickoffs for 223 yards, a 24.8-yard average, per Field Level Media, which also credits him with 1,295 all-purpose yards in his career. The Detroit Free Press offered the context that explains his grip on the role: Kennedy is the longest-tenured player in the organization, and he was only signed to the active roster three days before the opener against New Orleans, after the team released veteran Greg Dortch at the end of the preseason and suddenly needed a punt returner it could trust. Kennedy was the answer in September. Now someone else has to be the answer in October.

St. Brown Is the Emergency Plan, Not the Plan

Sunday's emergency solution tells you both how resourceful Detroit is and why it cannot last. Star receiver Amon-Ra St. Brown stepped in on punts and promptly ripped off two returns for 36 yards, including a 31-yarder that set up a Lions touchdown, per Field Level Media. Khalil Dorsey took over on kickoffs alongside Jacob Saylors, the Detroit Free Press reported. It worked for one afternoon. It is not a sustainable arrangement to send your most important offensive weapon back to field punts in traffic every week, and Campbell said as much on Monday: "I would rather not have St. Brown back there for a whole game," the coach told reporters, via the Free Press, adding that St. Brown might still handle situational returns depending on field position.

The search is already underway. The Free Press reported that practice-squad receiver Dominic Lovett is among the in-house candidates being considered, and that general manager Brad Holmes and his scouting staff have begun looking at external options as well. Detroit Football Network added Keys and Jackson — practice-squad receivers Lawrence Keys and Lucky Jackson, both of whom returned punts in the UFL this spring — to the list of names in the mix. The saving grace is the calendar: with the bye this week, Campbell noted the Lions are not crunched to decide immediately. They get two full weeks to audition a returner before Green Bay visits on October 25.

Devin White Went Down in the Same Game

Kennedy was not the only veteran Detroit lost on Sunday. Linebacker Devin White broke his forearm in the first half against Arizona and is likewise expected to need surgery, Pro Football Rumors reported, with Campbell acknowledging after the game that surgery looked likely and lamenting the timing for a player who had been doing good things for the defense. White's route to Detroit was a winding one — he piled up 174 tackles with the Raiders in 2025, per Pro Football Rumors, yet waited until August for a contract, then started all three of his appearances this season while carving out a rotational role behind Jack Campbell and Derrick Barnes. Whether White returns this season is unclear, which leaves Detroit's linebacker depth as the defense's version of the returner problem: manageable in a bye week, urgent by the next kickoff.

The Bye Week Just Became a Working Week

There is a version of this story that is purely grim, so let's be fair about the standings: the Lions are 3-2, they just hung 45 points on a road opponent, and their best player spent Sunday proving he can moonlight as an elite punt returner in an emergency. The machine mostly works. But championship teams are separated in the margins, and Kennedy was a margin — ten hidden yards a game, a sure pair of hands under a hanging punt, a veteran who had been in the building longer than anyone. Detroit will find a replacement; Holmes always seems to find somebody. The question is whether the replacement holds the standard, because the next time a punt hangs in the air with a game on it, there will be no bye week to hide behind.
