Allen (quadriceps) was a limited participant in Monday's training camp practice, Stu Jackson of the Rams' official site reports.
Allen has been limited to side work in training camp while recovering from a quadriceps injury, but his ability to practice Monday, even in a limited capacity, is a positive sign for the 2023 fifth-rounder. He's unlikely to play in Thursday's preseason finale against the Chargers, but Allen is working his way toward being available for the Rams' regular-season opener against the 49ers on Thursday, Sept. 10.
