Colts Activate Will Mallory as Tyler Warren's Groin Injury Clouds Sunday's Game Against the Titans

INDIANAPOLIS

The Indianapolis Colts made the move everyone expected on Saturday, and the reason they had to make it is the part nobody in Indianapolis wanted. The Colts activated tight end Will Mallory from injured reserve, according to Reuters and Field Level Media, one day after fellow tight end Tyler Warren — the team's leading receiver — was listed as questionable with a groin injury sustained in practice. Mallory's own questionable tag was lifted with the activation, clearing him to play Sunday at Lucas Oil Stadium against the Tennessee Titans. Warren's status, as of Saturday afternoon, had not changed. That gap between those two sentences is the Colts' whole weekend.

What happened to Warren on Friday

The injury arrived at the worst possible moment in the week, and in about the most Friday way imaginable. Per the Indianapolis Star, Warren was hit in the groin during the portion of practice open to the media on Friday, and he finished the day as a limited participant before the Colts listed him questionable. Head coach Shane Steichen offered the only update available, via the Star: "I'll check with the trainers and see where that goes."

That is coach-speak for "we genuinely do not know yet," and the Colts' actions since suggest they are planning for both worlds. The Star reported one small mercy on Saturday: Warren had not been downgraded. In NFL injury-report language, silence on Saturday is not good news, exactly, but it beats the alternative. Game-day inactive lists will tell the real story roughly 90 minutes before kickoff.

Why Warren matters this much

Strip the names away and look at the production. Warren has 30 catches for 213 yards and two receiving touchdowns in five games, all starts, per Reuters and Field Level Media, plus a rushing touchdown. The Star notes he is coming off his best receiving game of the season — seven catches for 83 yards and a 1-yard rushing score in last Sunday's 34-22 loss to the Pittsburgh Steelers — and that his 30 catches lead the team, even if Josh Downs edges him in receiving yards, 249 to 213, for a depleted Colts receiving corps.

This is also not a one-month flash. Warren was a Pro Bowl selection as a rookie in 2025, per Field Level Media, and Athlon Sports put the rookie line at 76 catches for 817 yards and four touchdowns after Indianapolis took him in the first round out of Penn State. When Daniel Jones needs a completion that moves the chains or settles a drive, Warren is the first place this offense looks. Losing him — or getting a limited version of him — against any defense changes the geometry of the Colts' passing game. Against a desperate, winless division rival playing with nothing to lose, it changes the risk profile of the entire afternoon.

Mallory's long August, and his second chance

If there is a sympathetic figure in this story, it is the replacement. Mallory, 27, has been on injured reserve since Aug. 30 with a thumb injury suffered at the end of what the Indianapolis Star described as an excellent training camp. He missed the first five games of the season. The Colts opened his practice window on Oct. 7, per ClutchPoints, and he was a full participant in practice all week, per Colts.com — this activation was coming, Warren or no Warren. The injury just turned a nice comeback story into a potential starting assignment.

The player himself is a known quantity in a specific role. Indianapolis drafted Mallory in the fifth round in 2023 out of Miami — the 162nd overall pick, per ClutchPoints — and he has produced 23 catches for 252 yards in 24 career games across three seasons, in just 268 offensive snaps, per Field Level Media and the Star. Do the snap math and a picture emerges: when Mallory is on the field, the ball finds him at a strikingly high rate. He is not a blocker, the Star noted plainly — he is a receiving option with sure hands who has spent two seasons as insurance at this exact position. On Saturday, the policy came due. He also showed his receiving chops this summer, catching six passes for 80 yards in the preseason opener against New England, per ClutchPoints, before the thumb injury stole his September and half his October.

The rest of the room tells you why this move mattered

Beyond Warren and Mallory, the Colts' tight end depth chart is essentially a run-blocking unit with jerseys in the tight end room. The Star ran the numbers: Mo Alie-Cox, the in-line tight end, has three catches for 30 yards; Drew Ogletree has one catch for four yards while working mostly as a blocker who lines up in different spots; and veteran Pharaoh Brown was brought up to the 53-man roster this week as another blocking option. All three are professionals at what they do. None of them replaces what Warren does to a defense's coverage rules.

That is the real stakes of Sunday's inactive list. If Warren plays at full strength, Mallory is a useful second receiving tight end and the Colts' offense looks like itself. If Warren is out or limited, Indianapolis either asks Mallory — who has not played a regular-season snap since last season — to absorb a starter's receiving load in his first game back, or it shrinks the playbook toward the run game and asks its blockers to be something they are not.

The wider picture for Sunday

The rest of the injury report adds context. Colts.com reported Friday that Steichen ruled out linebacker Jaylon Carlies (ribs) and wide receiver Ashton Dulin (hamstring), both of whom also missed the Week 5 loss in Pittsburgh. Tennessee ruled out defensive tackle Jordan Elliott (personal matter) and safety Kevin Winston Jr. (quadriceps). Running back Tyjae Spears (knee) and cornerback Joshua Williams (pectoral) are questionable.com.

The standings frame the urgency. Indianapolis is 2-3, per Reuters, coming off that 34-22 loss to the Steelers, and cannot afford to donate a home game against an 0-5 Tennessee team, no matter how many tight ends are limping. The Titans, meanwhile, get their best shot at a first win precisely because the Colts' most reliable pass catcher spent Friday afternoon talking to trainers. Sunday's game will start telling its story 90 minutes early, when the inactive list posts and one name is either on it or not. Until then, Will Mallory waits — healthy at last, activated at last, and possibly about to play the biggest game of his career because of a practice rep nobody will remember by Monday.
