FRISCO, Texas — Defensive end David Irving is returning to the Dallas Cowboys after signing a $2.9 million, one-year offer as a restricted free agent.

The Cowboys could have matched any offer for Irving after giving him a second-round tender. Irving reported for the start of off-season workouts Monday and signed the contract.

Irving was suspended the first four games last season for violating the NFL's ban on performance enhancers and missed the last four with a concussion. In between, he had seven sacks in eight games, second on the team behind Pro Bowl selection DeMarcus Lawrence.

The Cowboys signed Irving off Kansas City's practice squad in 2015. The 24-year-old has 11 sacks over three seasons in Dallas.
