Higbee injured his ankle during Sunday's contest versus the Seahawks, Stu Jackson of the Rams' official site reports.
Prior to limping off the field late in the third quarter, Higbee had one catch (on two targets) for 23 yards. The TE trio of Colby Parkinson, Davis Allen and Terrance Ferguson will fill in for Higbee for as long as he's sidelined.
