Jordan Reed’s latest concussion might end his career.

According to ESPN, the Washington Redskins tight end may not be able to return to the NFL after suffering a concussion during the team’s third preseason game on Aug. 22, with people within the organization concerned Reed’s career could be over.

Reed, who’s in his seventh season in the NFL after being selected in the third round of the 2013 draft, has suffered multiple concussions throughout his career, though the exact number isn’t clear.

The 29-year-old still hasn’t been cleared after his latest concussion and has been ruled out for Monday night’s game against the Chicago Bears. He would like to keep playing, per ESPN.

Reed, who’s also dealt with other injuries during his career, has been an impact player for Washington when healthy. In 2015, he caught 87 passes for 952 yards and 11 touchdowns in 14 games. The following season he made the Pro Bowl while recording 66 receptions for 686 yards and six touchdowns.

He played just six games in 2017 and last season had 54 catches for 558 yards and two TDs in 13 games.
