NFL reviews Dielman’s concussion

The NFL is looking into the events surrounding a concussion suffered by San Diego Chargers offensive lineman Kris Dielman.

NFL vice president Bryan McCarthy said the league is reviewing the injury with the team, medical staff and NFL Players’ Association. McCarthy said in an email Friday that the review is ongoing.

The NFLPA declined comment until it receives more information. There’s an inquiry into Dielman’s concussion because of some unusual circumstances surrounding the injury.

He was concussed with 12 minutes remaining in the Oct. 23 game against the New York Jets, after which he struggled to maintain balance.

He finished the game despite the head injury and was not assessed until after the loss to New York. The Chargers announced the injury shortly before the team boarded a plane for San Diego.

Dielman suffered a grand mal seizure near the end of the team’s charter flight, although he was cleared of all long-term complications surrounding the concussion and seizure.
