Colts' center Jeff Saturday has no timetable for his return to the field after suffering a knee injury, according to Indianapolis Star. Saturday won't have surgery, but rehabilitation might take longer than he would like. "All you can do is your rehab and progress the way they want you to progress and when it's time to go, I'll be ready to go," Saturday said. He will not play Sunday against the Bears. "I'm not going to go get surgery unless something else happened to it," he added. "I'm going to stay with the way it is now." After tearing the medial collateral ligament in his knee on Aug. 24, surgery would have almost definitely kept him out until late November or December.
