The Buffalo Bills have suspended offensive line coach Aaron Kromer without pay for the first six games of the season.

"The suspension will begin on Monday, September 7, 2015 and end with the conclusion of the Buffalo Bills vs. Cincinnati Bengals game on October 18, 2015," Bills president Russ Brandon said in a statement Sunday night. "We worked in conjunction with the NFL on this matter and we are highly supportive of the NFL Personal Conduct Policy that holds all NFL club employees to a higher standard."

Kromer was with the Bills in training camp practice Monday. He had been on indefinite paid administrative leave as Buffalo began training camp Friday morning.

He will leave the team again at the start of the regular season and will be eligible to return to work for the Bills' Week 7 game against the Jacksonville Jaguars that will be played in London.

Kromer and his son Zachery had battery charges against them dropped earlier this week. The charges stemmed from a July 11 incident in which Aaron Kromer was alleged to have punched a boy in the face and threatened to kill his family in a dispute over beach chairs. Zachery Kromer was accused of placing his hands on another boy during the altercation.

An arrest report released by the Walton County Sheriff's Office said Kromer threatened to kill one of the boy's families if he reported the incident.

Assistant offensive line coach Kurt Anderson assumed Kromer's duties while he was on paid leave. And Anderson is expected to take over once again during Kromer's suspension.

Buffalo is in its first training camp under coach Rex Ryan, who brought in Kromer after his two-season stint as the Chicago Bears' offensive coordinator.

On Sunday, Ryan said there remains an offensive-line competition at right guard and right tackle. He listed left guard Richie Incognito, center Eric Wood and left tackle Cordy Glenn as players he regards to have earned starting jobs.
