From watching the game footage, it looked Dielman, while trying to push at the line during a Mike Tolbert run up the middle, slammed helmet-first into Calvin Pace. After the play was dead (and the Chargers had lost a yard), Dielman stumbled backwards around 15 yards before losing his footing and falling onto the field. Despite this, Dielman stayed in the game and didn't undergo testing until after the game ended.
However, according to ESPN, Dielman suffered a grand mal seizure on the Chargers' chartered flight back west. Dielman has yet to take the NFL's concussion test or be cleared to play and will likely miss at least two games. According to head coach Norv Turner, the Chargers handled the situation exactly as they should have:
"Everything was handled extremely well," Turner said. "All the proper precautions were taken. Kris was evaluated when we landed and all the tests were excellent. We're fortunate, he's fortunate and we're moving on."The NFL doesn't think so. According to vice president Bryan McCarthy, the NFL, along with the Chargers, their medical staff, and the NFLPA, is reviewing the response to the injury. Just another reminder of how dangerous football can be, even away from the ball.
