PITTSFORD -- An injury to John Miller during Monday's practice provided a glimpse into how the Buffalo Bills view their options along the offensive line.
Stepping in for Miller at right guard was Ryan Groy, who to this point in training camp has worked exclusively at center, alternating with Russell Bodine between the starters and second unit.
Coach Sean McDermott puts a heavy emphasis on position flexibility, so it's telling that Groy was inserted with the starters. Miller eventually returned to the field, although he sat out the remaining drills, so his injury did not appear to be serious. If he misses any time, it will be interesting to see if Groy stays in the starting spot.
2. Trent Murphy remains out, opening the door for Shaq Lawson.
With defensive end Trent Murphy still nursing a groin injury, 2016 first-round pick Shaq Lawson has had a chance to work with the starters along the defensive line. Lawson recorded a would-be sack and a pass defensed during Monday's practice, in addition to disrupting the pocket on a few other plays. The Bills also continue to work him in at defensive tackle on third downs.
It was easy to think of Lawson when General Manager Brandon Beane was answering a question about the trade for wide receiver Corey Coleman.
Browns General Manager "John (Dorsey) wasn’t there to pick him in the first round," Beane said. "I think it’s a little different when you have a new regime and you’re a little less attached. If this guy’s not doing everything you want every day, then 'I didn’t pick him.' "
3. Robert Foster struggling to make plays.
One of the early sleeper candidates for the 53-man roster was receiver Robert Foster. The undrafted free agent from Alabama has the size-speed measurables teams like. Foster, however, has noticeably cooled off after a hot start to camp. He had a bad play during the final segment of 11-on-11 work in the red zone Monday, double clutching a pass from AJ McCarron that allowed the defender to tip the ball in the air. That led to an interception -- likely a pick six -- for safety Rafael Bush. The addition of Coleman will only make it tougher for Foster and other receivers fighting for a roster spot.
4. Kaelin Clay returns to practice.
The Bills got one of their two injured receivers back, as Kaelin Clay participated Monday. Rookie undrafted free agent Cam Phillips remained out, joining Murphy as the two non-participants. Receiver Zay Jones continued to sport a red non-contact jersey as he makes his way back from knee surgery.
