The Cowboys previously signed eight players including:
- WR Donte Foster
- DE Mike McAdoo
- DB Brandon McGee

- DB Buddy Jackson

Future/reserve contracts are essentially an opportunity for players compete for a roster spot in offseason workouts and training camp.
Renfrow, 26, originally signed on with the Cardinals as an undrafted free agent out of back in 2014. Since then, Renfrow has had brief stints with the Packers and Seahawks before signing on with the 49ers in May of last year.
Unfortunately for him, he was among their final roster cuts at the start of the season, but later returned to the team in October.
He has yet to appear in an NFL game.
