Keenan Allen, DeForest Buckner and Sauce Gardner make key plays as Colts close preseason with Lions test

The Indianapolis Colts closed their 2026 preseason with a slate of decisive, game-shaping moments on Saturday against the Detroit Lions. In the kind of final tune-up that typically matters most for evaluation, the Colts got a 24-yard reception from Keenan Allen, effort plays from defensive line veteran DeForest Buckner, and an interception from cornerback Sauce Gardner that underscored their emphasis on finishing drives and protecting the ball late.

Allen’s impact came through as a reliable downfield presence in the passing game. According to the Colts’ recap, Allen hauled in a 24-yard catch that helped move the offense forward when the preseason stage was at its highest leverage point. For a team trying to sharpen timing and routing concepts, plays like that offer immediate feedback for what works with live defensive looks.

On the defensive front, Buckner’s presence showed up in the hustle-and-hold phases of the game. The team’s account highlights that Buckner “hustled for a tackle,” an emphasis that is often less about highlight reels and more about base competitiveness. In preseason finales, coaches frequently look for whether starters can sustain effort through rotations and whether the defense responds physically when plays break the first read.

Gardner’s headline defensive moment came as a takeaway. The Colts’ report states that Gardner picked off a pass, a reminder that his value is tied not just to coverage responsibilities, but to creating swing plays. In preseason, interception totals can vary widely, but the process matters. A clean break and secure finish indicates readiness for the speed and route timing that arrive early in the regular season.

Taken together, the three featured players represent a blend of roles the Colts will need as they move from evaluation to execution. Allen’s production supports the passing-game rhythm. Buckner’s closing speed supports the run-defense and scramble situations. Gardner’s interception speaks to the secondary’s ability to convert coverage into possession.

The Colts’ next step is the transition most teams face right after the last preseason game: converting what they saw into a stable regular-season rotation, where every snap has more consequence. For fans, the immediate watch point is whether these momentum-building moments carry into Week 1 preparation and whether the team’s offensive and defensive identity holds when the preseason tempo is replaced by regular-season stakes.

As with any preseason recap, details beyond the three highlighted plays are limited here, so the broader statistical picture is not the focus of this report. Still, the message from Indianapolis is clear: the Colts wanted standout efforts from key veterans, and they got them at the end of the preseason calendar.
