Seattle Seahawks guard James Carpenter left the game against the Chicago Bears in the first quarter after tweaking his left knee. After X-rays and an MRI, head coach Pete Carroll said Monday that there doesn't appear to be any major problem with the left guard's knee, yet there is no timetable for his return, according to the Seattle Times.
The injury is to the same knee that required ACL surgery last year.
Carroll added that Carpenter felt a "sharp pain" in the knee, and the injury was a separate issue after Carpenter left the previous game against Miami only to return, according to The News Tribune.
Second-year pro John Moffitt replaced Carpenter at left guard and will continue to do so, though Carroll said that rookie J.R. Sweezy, who saw time early in the year because of injuries, will start getting geared up to play. Sweezy has been inactive the past few months.
Carpenter, a first-round pick from the 2011 draft, also missed time this season because of a concussion.
