Arizona Cardinals quarterback Colt McCoy is still in the concussion protocol and won't play on Christmas night against the Tampa Bay Buccaneers, coach Kliff Kingsbury announced Wednesday.
Trace McSorley will make his first NFL start on Sunday night with McCoy sidelined.
McCoy, who was starting in place of the injured Kyler Murray, who tore an ACL in a Week 14 loss to the New England Patriots, suffered a concussion this past Sunday in a loss to the Denver Broncos.
McSorley finished the game and was 7-of-15 passing for 95 yards and two interceptions.
