Cordy Glenn returns while Buffalo Bills lose two to torn ACLs

ORCHARD PARK, N.Y. -- After missing more than three weeks with an ankle sprain, Buffalo Bills left tackle Cordy Glenn has returned to practice, working in individual drills beginning Sunday. Glenn won't play in Thursday's preseason finale against the Lions, but he should be ready for the season opener in Baltimore.

"Sometimes guys think they need it. I don't," coach Rex Ryan said of Glenn playing in the game. "I think we will simulate it in practice. So ... I don't think he'll play."

Ryan said almost all of his starters are going to sit out the final game. "There are going to be guys that are playing that are going to be on our football team, without question," he said. "Safeties are going to have to play. ... I don't think it's clear who is shaking out. It will be good for Manny (Lawson) to play some more. He missed that time with the pec, so I think you can see someone like him getting in there and getting some reps."

Safety Aaron Williams and running back Mike Gillislee participated in the portion of practice open to the media, a good sign as they advance through the NFL's concussion protocol. To be able to practice, both players must have reached baseline levels of functioning in neurophysiological testing, as determined by an independent consultant.

Meanwhile, the Bills suffered two more season-ending ACL injuries in their loss to Washington. Cornerback Jonathan Dowling, who was probably a longshot to make the team, and tight end Chris Gragg, a fourth-year player who was enjoying a very good preseason and was firmly on the roster.

Gragg went down when he was struck on the knee by Redskins safety DeAngelo Hall went low to take him down on a pass over the middle. Hall, who a few plays earlier leveled a cheap shot on a Bills running back and was penalized 15 yards, could have tackled Gragg higher and the hit bordered on being dirty and Ryan was not happy about it.

"It's a real shame," Ryan said. "Sometimes, especially with Gragg's injury, a guy should make a tackle. But I get it. Was frustrated he just had a 15-yard penalty. That was ridiculous in my opinion, but it is what it is."

Gragg and Hall engaged in some Twitter back and forth after the game and Hall said, "No disrespect to the #Bills Player, I wish him nothing but the best. But I play 1 speed and that's all out. That's why I been here 13 years." In another tweet, Hall said, "I'm playing within the rules. If that hit was so dirty tell the league to fine me or throw a flag. And the one flag the whistle didn't blow."

NOTES: Linebacker Manny Lawson finally talked about the NFL's ongoing investigation into an alleged violation of the league's personal conduct policy, acknowledging there was an incident in 2014 in which Lawson was charged with misdemeanor disorderly conduct/domestic violence. He said there was no physical violence, and that case was dismissed after he completed a diversionary program. ... "(It was) disorderly conduct, domestic because it happened at home," Lawson said. "No physical violence. I'm being investigated and we'll see what the NFL has to say about it." ... WR Marquise Goodwin is still in concussion protocol and has not returned to practice. ... CB Nickell Robey-Coleman missed the Washington game with a quad contusion, and he also is battling an ankle injury. ... RB Jonathan Williams could not finish the Washington game after suffering a rib injury, and he did not practice Sunday.
