Bills' Dareus upbeat after suspension; McDermott reacts

Bills' Tyrod Taylor remains in concussion protocol

McDermott said Dareus' actions ticked him off "well enough to get sent home".

Since McDermott was hired as head coach, he's preached accountability, character and discipline - three traits that Dareus hasn't shown throughout his career with the team.

One thing McDermott was able to address was his player's past history with trouble, as Dareus has been suspended twice by the National Football League in his six-year career. We got a clear understanding now. "I'm focusing on zoning in wholeheartedly and any confusion I have, I'm coming straight to him to make sure the water's clear".

Taylor is still in the concussion protocol and won't practice Tuesday, ESPN's Mike Rodak reports.

"Anytime guys are injured it is concerning", McDermott said.

In regard to Bills fans, Dareus had this message: "I'm going to do everything in my power to move forward, stay focused". I really believe that. The 27-year-old has violated the NFL's substance abuse policy multiple times, leading to a four-game suspension last season.

In no surprise, Taylor will also not practice.

The Bills are down to one healthy quarterback, so they've made a decision to add a passer for Thursday's final preseason game.

Yates, 30, also sustained a concussion during Buffalo's 13-9 loss to Baltimore.

McDermott did not narrow it down exactly when Yates suffered the injury, just said it was late in the game.

Rookie Nathan Peterman and newly signed Keith Wenning are the only two healthy quarterbacks on the roster, with McDermott admitting he's mindful that Peterman could be the team's season-opening starter.
