Ferguson (ankle) is out for Sunday's game against Philadelphia, Nate Atkins of The Athletic reports.
Ferguson sprained his ankle last Sunday night against the Broncos and didn't practice at all this week, so this comes as no surprise. If Colby Parkinson (shoulder/knee) can play through his injuries, the Rams would be in better shape at tight end. If not, Tyler Higbee and Davis Allen figure to see heavy snaps against the Eagles.
