Allen (head) returned to the Week 1 contest against the 49ers, Stu Jackson of the Rams' official site reports.
Allen exited early in the contest with a potential concussion. The tight end's confirmed return to the Week 1 contest in Australia means an independent neurologist deemed that he did not have a concussion and was all set to play. Allen should be ready to practice throughout Week 2 and suit up for Monday's game against the Giants.
