Carolina Panthers veteran tight end Greg Olsen will not return in his team's Week 13 matchup with the Washington Redskins after suffering what could be a concussion. Olsen, 34, a thirteen-year pass-catching blocker, is heading to concussion protocol, per Panthers reporter Max Henson on Twitter.

The 6-foot-5 Olsen has appeared and started in all twelve Panthers games this season after only playing in a combined 16 games the past two years. Entering Sunday, Olsen had 530 receiving yards on 45 receptions and two touchdowns.

At 34 years old, the future is uncertain for Olsen, and the possible concussion sustained against the Redskins today may further muddy whether the veteran tight end stays with Carolina. Olsen signed a two-year extension with the club prior to the 2018 season, so along with veteran quarterback Cam Newton, the Panthers could see an end to the generation of football between two long-time members of the squad.

Olsen previously mentioned he was unsure if he'd keep playing, citing his health as a determining factor.

“I don’t know what the future holds. I think a lot of it just has to deal with staying healthy. If I can stay healthy, I can still produce as good as anybody in this league. I’ve shown that. It’s just a matter of your body holding up,” he said.

Olsen is a three-time Pro-Bowler who begun his professional career with the Chicago Bears but has since spent nine seasons in a Panthers uniform.

Olsen broke his foot in the 2017 season and re-fractured it the next year. Add a potential head injury inflicted on Sunday against Washington, and the tight end may be on his way out of the NFL.
