Colombo working in personnel department

IRVING, Texas – Three years after he played his last game in the NFL, former Dallas Cowboys offensive tackle Marc Colombo is checking out life on the personnel side of the NFL.

Colombo, who started for the Cowboys at right tackle from 2006-10 and finished his career in 2011 with the Miami Dolphins, is working in the scouting department this summer.

“Marc’s obviously a very smart guy and knows what he’s doing and he was always a leader in that offensive line room,” executive vice president Stephen Jones said. “He knows what guys look like. He’s testing the water in a lot of areas. We’re giving him some projects, see what he likes. He’s obviously a guy who did a lot for the Cowboys.”

Colombo spent most of his time observing the offensive line on Friday and Saturday, but he talked to multiple coaches, including special-teams coordinator Rich Bisaccia.

“He’s got great energy,” coach Jason Garrett said. “Always has, always will.”
