FOXBOROUGH -- The Patriots have signed 23-year old safety Cyhl Quarles to the team's eight-man practice squad, releasing converted tight end Alex Silvestro in the process.
Quarles is a rookie free agent out of Wake Forest. He originally signed with the Baltimore Ravens but was released Aug. 31. At 6-3, 212 pounds, he appeared in 50 games for the Demon Deacons and totaled 239 tackles.
Silvestro, who originally signed with the Patriots as an undrafted rookie defensive lineman in 2011, made the switch to tight end this year, after a year on the practice squad. He was cut from the team again this year after training camp, signing to the practice squad a day later.
