The Patriots announced on Saturday the signing of offensive tackle Zack Roth, as well as the release of veteran linemen Chris Morris and Steve Williams.
The 6-foot-6, 319-pound Roth is an undrafted rookie from TCU who started 10 games at right tackle last season opposite Pats' fifth-round selection Marcus Cannon. The pair helped block for an offense that set single-season school records in touchdowns (73), points scored (541) and total offense (6,199 yards).
Morris is a 6-foot-4, 305-pound offensive lineman that has seen time at center, guard and long snapper in five previous NFL seasons. A seventh-round draft pick out of Oakland in 2006, Morris has played in 51 games for the Raiders and Panthers and has made 11 starts. He was signed by the Patriots on Aug. 3.
Williams is a 6-foot-2, 306-pound defensive lineman who was undrafted in 2006, but previously spent time in the Chiefs' and Panthers' organizations. After being signed and waived by New England in 2009, Williams spent the last two seasons playing for the BC Lions of the Canadian Football League before signing again with the Patriots on July 30.
