OXNARD, California We have had our first fight of 2013 at Dallas Cowboys training camp.

On consecutive plays, linebacker Ernie Sims handled running back Lance Dunbar roughly at the end of the runs. The second time, Sims shoved Dunbar to the ground.

Dunbar refused to back down and pushed Sims, and a ruckus ensued.

No punches were thrown, just a good deal of pushing and shoving as other players quickly moved in to defuse the dispute.
