INDIANAPOLIS, Ind. — On Thursday, the Indianapolis Colts released their penultimate injury report for Sunday's game against the Atlanta Falcons in Berlin, Germany, and star defensive tackle DeForest Buckner has already been listed as out with his neck injury.

Buckner was declared out before the final injury report was released because he is not traveling with the team to Germany on Thursday evening.

Perhaps the most critical player on the Colts' defense, Buckner will be missed in a showdown featuring a Falcons run game that boasts Bijan Robinson.

The Colts' run defense currently ranks fourth in the NFL, allowing just 87.0 yards per game. Their 4.0 yards per carry allowed is tied for ninth. The Colts are also tied for sixth in the NFL with 26 sacks.

Buckner has started all nine of the Colts' game this season, totaling 42 tackles, 4.0 sacks and team-highs in tackles for loss (9) and quarterback hits (13).

In Buckner's absence, the Colts will likely start Neville Gallimore at three-tech defensive tackle next to Grover Stewart at nose tackle. Adetomiwa Adebawore will also see more action.

Gallimore has 21 tackles (3 for loss), 2.5 sacks, 5 quarterbacks hits, and 2 pass breakups this season. Adebawore has 14 tackles (2 for loss), 1.5 sacks, 3 quarterback hits, and 1 fumble recovered.

The Colts and Falcons play this Sunday, Nov. 9, at 9:30 a.m. ET on NFL Network at Olympic Stadium Berlin.
