Camp began with the offensive line being mostly set, with the Cardinals only needing to fill the right tackle spot. However Levi Brown tore the triceps in his right arm during the preseason, leaving the team scrambling to fill both tackle positions.

Jeremy Bridges

The veteran Bridges began training camp as the starting right tackle, and it's possible Brown's injury may slide him to the other side.

Bridges has not received as much playing time in preseason because, as head coach Ken Whisenhunt has said, the team knows what he can do, and as it is that may be better than the other options.

Bobby Massie

A fourth-round pick out of Ole Miss, it was hoped Massie would eventually take over the right tackle position when he was ready, not out of necessity.

However, the 23-year-old may be pressed into duty due to injuries along the line, and he's getting a test run as a starter in Thursday's preseason finale against the Broncos.

D'Anthony Batiste

A career journeyman, Batiste is getting the start at left tackle Thursday against the Broncos after playing well in Tennessee last week.

Another good effort could lock up the starting job.

D.J. Young

D.J. Young got the start against the Titans last week and, well, struggled a bit. The second-year pro had trouble staying in front of whoever lined up opposite him, and likely cost himself a shot at the starting job for now.

That said, the Cardinals are still excited about Young's potential and will not give up on the 24-year-old just yet.
