Reagor was diagnosed Wednesday with a UCL tear in his thumb, Zach Berman of The Athletic reports.
Reagor was merely a spectator at Wednesday's practice, and the reason for his absence now is clear. According to Mike Garafolo of NFL Network, Reagor played through the injury in Sunday's loss to the Rams, but the rookie wideout is now a candidate to miss some time. How much time is the question, but Reagor seems to be trending toward an absence for at least the Eagles' Week 3 game versus the Bengals.
