The Cowboys made a move to shore up their depleted linebacker corps with the signing of Keith Smith Friday.
Smith was one of two linebackers who were given tryouts by the team after the morning practice. Veteran Lawrence Wilson was other.
The Cowboys ultimately signed Smith, who is familiar with team after opening last season on the practice squad before playing 10 games as a rookie in 2014. He spent much of the off season with the Cowboys before being cut in May.
The Cowboys needed to add depth because they lost Keith Rivers to retirement before the start of camp and is practicing without the injured Rolando McClain (PUP) and rookie Mark Nzeocha (NFI).
The Cowboys also moved center Shane McDermott from the non football injury list to the active roster. McDermott, an undrafted rookie from Miami, missed the first day of camp because of an eye issue.
The Cowboys have 89 players on the roster. They have one roster spot available.
