The Cardinals’ offensive line, which was porous for much of the first half of Friday night’s preseason game against the Raiders, could have a big hole on the left side.

Tackle Levi Brown left the game with a triceps injury.

As Darren Urban of the team’s official website points out, it could be a major problem.  Torn triceps muscles often result in season-ending surgery.

Brown’s backup is D.J. Young, who was undrafted in 2011 and who didn’t appear in a single game.
