Hardwick had surgery on his sprained right foot on March 14. The team said at the time that he would need four to six months to recover.
Hardwick was hurt early in a game against the Oakland Raiders on Oct. 14 and missed the next four games. He played in the final six regular-season games and three playoff games.
He's played mostly at center, but also at guard and tackle.
A veteran of 10 NFL seasons, Newberry (6-5, 315) has played in 104 career games and has started every game in which he's appeared. While his most significant action has been at center, Newberry has also started at guard and tackle during his career.
