Cardinals' Tony Jefferson diagnosed with concussion, doesn't remember playing in game
Friday October 31st, 2014

Arizona Cardinals safety Tony Jefferson said he doesn't remember playing against the Eagles after he suffered a concussion during the game, Josh Weinfuss of ESPN reports.

Jefferson, who said he thinks the concussion happened during a kickoff, was diagnosed with a concussion on Monday. He realized there was a problem when he was driving after the game on Sunday. 

"I don't really remember the game," Jefferson said. "I just remember when I started driving ... I just stopped for 30 minutes. I was like, 'What just happened?' I don't remember what happened. It was kinda scary.

"I went home and watched the film on the iPad. It was like seeing you on auto pilot. It was pretty weird."

Jefferson finished the game with 11 tackles and passed the concussion protocol on Thursday. His status for Sunday's game against the Dallas Cowboys is uncertain, but he said he is focused on his long-term health, according to the report.

"This is your brain you're talking about," he said. "You don't want to do anything like that. I'm just going to see what they say but I feel fine.

"We got a long season ahead of us; I don't want to rush back."

He is in his second season out of Oklahoma and has 44 tackles, 1.0 sack and one pass defended this season.

The Cardinals play at the Cowboys on Sunday at 1 p.m.
