Speaking after practice on Saturday, Carroll said the range for treatment is still unknown. He said Harvin could be back on the field in a couple of weeks, or surgery may be the solution to solve the discomfort in the area around Harvin's hip socket.
Harvin's exam is expected to be on Tuesday. Carroll has not said which hip is bothering the wide receiver.
Seattle fullback Michael Robinson also missed a second straight day of practice on Saturday with a sore ankle. Carroll said Robinson came in after the first day of practice saying it was sore, but not a sprain.
Carroll added that tight end Zach Miller could return soon from a sore foot.
