ESPN’s Adam Schefter reports DJ Moore (shoulder) is “not a lock” to play in Week 3 against the Chargers.

This is already shaping up to be an injury that will be monitored throughout all of next week. Moore is believed to have suffered an AC joint sprain in the Bills’ Week 2 win over the Lions, and while the injury isn’t considered serious, sources familiar with the situation haven’t ruled out the possibility that he’ll miss at least one game. Moore was held without a catch on Thursday after catching five passes for 100 yards and a touchdown in Week 1. Moore’s absence could open the door for Keon Coleman to see more work. Coleman played on 55 snaps against the Lions after playing on just 29 in Week 1, and caught all six of his targets for 63 yards.
