What happened to Marvin Harrison Jr? Live injury updates for NFL Week 6 on Sunday 10/12/25

Updated:

By: Sean Barnard

UPDATE: Marvin Harrison Jr. has been ruled out for the remainder of today’s Cardinals vs. Colts game and has been diagnosed with a concussion.

All qualifying bets on Marvin Harrison Jr. will be honored on DraftKings Sportsbook by the Early Exit.


The injury bug is out and biting today, with the Arizona Cardinals being one of the victims. Marvin Harrison Jr. left today’s matchup with the Colts due to a head injury and is being evaluated for a concussion.

Harrison Jr. made a catch coming across the middle, and his head snapped back hard on the turf following the tackle. The Cardinals’ pass-catcher got up a bit slowly and was taken into the blue medical tent to be evaluated. Harrison Jr. has since been brought into the locker room for further evaluation. He had two receptions for 32 yards before leaving the matchup.

This is a matchup that holds a bit of extra weight as it is Harrison Jr’s first time playing in Indianapolis. His father, Marvin Harrison, spent all 13 years of his Hall of Fame career playing for the Colts. It has been an underwhelming start to the highly ranked wide receiver prospect, but the talent of Harrison Jr. still pops in certain opportunities.

His status will continue to be monitored, and more updates will be added as the team provides them.

This also comes following Kyler Murray not being able to suit up at all today due to a foot sprain, and RB Emari Demercado is also in the locker room with an ankle injury.
