Offensive tackle Ryan Harris will begin his seventh NFL offseason with the Houston Texans. Harris, whom the Texans signed on September 1 of last year, signed a one-year deal to remain with the Texans on Monday. He played in all 16 games in some capacity, beginning the season on special teams last year, and started in two games. Harris was signed to add depth to the line after tackle Rashad Butler tore the triceps in his right arm during training camp and was placed on injured reserve. Harris added a veteran presence to a right side that lacked experience as young players worked into the starting lineup. Second-year Derek Newton started 14 games at right tackle and battled leg injuries during the season. Newton had reparative knee surgery in February. Harris spent the first four years of his career in Denver and was their starting right tackle in 2009 and 2010. He ended 2009 on injured reserve with a toe injury, missed five games in 2010 with an injury and missed most of the 2011 season due to an injury. But last season, Harris was active the whole season. The Texans also re-signed nickel corner Brice McCain this offseason to a three-year deal and reserve offensive lineman Andrew Gardner. They lost fullback James Casey and outside linebacker Connor Barwin to the Philadelphia Eagles and safety Glover Quin to the Detroit Lions. Cornerback Alan Ball and running back Justin Forsett signed with the Jacksonville Jaguars. Houston also signed three veteran free agents who’d left teams with which they’d spent the rest of their long careers: former Ravens safety Ed Reed, former Raiders punter Shane Lechler and former Jaguars fullback Greg Jones. As of Friday, the Texans had $3.81 million of space left under the salary cap.
