11:06pm: Branch is indeed appealing his one-game suspension, per NFL Network’s Ian Rapoport and ESPN’s Jeremy Fowler . However, the NFL’s language in their letter informing Branch of his suspension makes it seem unlikely that he will succeed.
“Your aggressive, non-football act was entirely unwarranted, posed a serious risk of injury, and clearly violated the standards of conduct and sportsmanship expected of NFL players,” the statement read (via Dave Birkett of the Detroit Free Press ).
4:30pm: Brian Branch
will be unavailable to the Lions in Week 7. The third-year safety was issued a one-game suspension on Monday, per a league announcement. 
After last night’s Lions-Chiefs game, Branch slapped Kansas City wideout JuJu Smith-Schuster (video link ). A brief skirmish ensued, leading to the expectation supplemental discipline would be handed down. The NFL reviewed the incident and issued the ban.
Branch has already been fined 13 times in his career despite only playing 41 combined regular and postseason games to date. Given his history in that regard, issuing a suspension does not entirely come as a surprise from the league’s perspective. The 2023 Pro Bowler can appeal the ban; if he does so, one of the jointly-appointed hearing officers will oversee the matter.
When speaking to reporters Sunday night, Branch admitted he should not have initiated the altercation with Smith-Schuster but added he felt the Chiefs were attempting to “bully” him during the game (video link via ESPN’s Eric Woodyard). Head coach Dan Campbell termed Branch’s actions “inexcusable,” meaning team discipline of some kind may have been forthcoming anyway.
Regardless of what happens on that front, the Lions are now set to be without a critical member of their secondary pending a successful appeal. Branch has operated as a full-time defensive starter for most of his career, and the former second-rounder recorded 109 tackles in 2024 while adding double-digit pass deflections for the second year in a row. Branch had enjoyed a productive start to his season, but he will now miss the final game before Detroit’s bye week.
The Lions’ secondary is already shorthanded with D.J. Reed on injured reserve and fellow cornerback Terrion Arnold out of the lineup as well. Branch has experience as a slot corner but his ideal position is safety, where he has formed an effective tandem with Kerby Joseph (who has himself battled injuries as well despite playing every game this season).
Detroit’s loss last night dropped the team to 4-2 on the year. The team’s secondary will face a strong test against the Buccaneers in Week 7, but that unit will be without a key figure.
