FILE - This is a 2009 file photo showing Houston Texans rookie cornerback Glover Quin(notes). Quin will miss this weekend's game against Jacksonville with what he calls concussion symptoms. Quin, who has started eight games this season, says he isn't sure if he had a concussion and if he did it was a mild one. Still, the Texans chose to sit him after he had headaches earlier this week.
