The team announced Saturday that Costa has signed a two-year contract. As a restricted free agent, he would have netted $1.323 million this season, so the deal allows Dallas to craft a more cap-friendly arrangement.
Costa, 25, barely played last season after back pain and a dislocated ankle limited him to three starts. He made every start for the Cowboys in 2011, and the offense definitely is a better unit when he's playing.
Losing him for the season one week later was a significant loss for the Cowboys, but he's now locked down through 2014.
