Cowboys add to D-line with Terrell McClain

The Cowboys made their first move of the free-agency period on Day 2 by reaching an agreement with defensive tackle Terrell McClain on a three-year deal, according to multiple sources.

McClain, a third-round pick by the Carolina Panthers in 2011, has played for three NFL teams, most recently the Houston Texans in 2013 where he played in 16 games and recorded eight tackles.

The Cowboys envision McClain as the pass-rusher inside, the three-technique position Jason Hatcher played last year and to create competition along the defensive line that is lacking depth.

McClain arrived at the Cowboys' Valley Ranch complex Wednesday.

When McClain was at South Florida, he worked out for then-Chicago Bears defensive coordinator Rod Marinelli. Now, Marinelli is the Cowboys' defensive coordinator and he's trying to find talent to fit his 4-3 scheme.

In the past 24 hours, the Cowboys lost three players along the defensive line. End Anthony Spencer hit the free-agent market, end DeMarcus Ware was released and reached an agreement with the Denver Broncos on Wednesday, and Hatcher also morphed into the marketplace and was visiting Seattle late Tuesday night.

There are only two projected starters left for the defensive line in end George Selvie and defensive tackle Nick Hayden.
