The Dallas Cowboys signed defensive end Lavar Edwards to their practice squad and released offensive lineman Ronald Patrick on Tuesday, according to David Helman of DallasCowboys.com.

This is Edwards' second stint with the Cowboys after he was released in early September. Before the most recent signing, Edwards was with Bears after the Raiders picked him up for their practice squad. Edwards was waived by the Bears last Friday.

The former LSU standout was the fifth-round draft selection of the Titans in 2013. He's played in 12 career games and has tallied 10 combined tackles.

Patrick, the offensive lineman, originally signed with the Cowboys in 2014 after going undrafted out of South Carolina. Patrick has bounced around from a few practice squads (Steelers and Panthers) since then, but did end up back with the Cowboys before the start of training camp this year. Patrick didn't make the Cowboys 53-man roster in September and was waived at that time before signing with the practice squad.

The Cowboys have their first practice of the week on Wednesday to prepare for the Saints on Sunday.
