Between injuries and ineffectiveness, the Arizona Cardinals have had plenty of issues on the offensive line this season, but two rookie offensive linemen continue to wait for their opportunity.

The Cardinals drafted Senio Kelemete in the fifth round and Nate Potter in the seventh round of the 2012 NFL Draft, but neither is yet to see much of the field. Potter has played one play this season, while Kelemente has been inactive for all eight games. Instead, both have focused on getting stronger and learning the playbook while they wait for an opportunity to play.

"You got to be ready. You never know when it could happen," Potter said, according to AZCardinals.com.

While they are yet to play significant roles this season, offensive line coach Russ Grimm said it's possible both could be in line for playing time before the season is over. With Levi Brown and Jeremy Bridges going down for the season during training camp, Potter and Kelemente moved up the depth chart and could now be just one play away.
