Cardinals' Cody Simon: Exits with knee injury

Simon (knee) is questionable to return to Sunday's game against the Texans, Darren Urban of the Cardinals' official site reports.

Simon appeared to injure his left knee in the first quarter, and he's being evaluated by medical staff to determine whether he can return. Baron Browning and Akeem Davis-Gaither are the top candidates to work with the first-team defense for as long as Simon is sidelined.
