Buffalo Bills guard Richie Incognito took the next step in his return to football following a 15-month hiatus for his role in the Miami Dolphins bullying scandal.

Three days into training camp, coach Rex Ryan named Incognito the team's starting left guard.

That's a significant step for Incognito, the eighth-year player who signed with Buffalo in January. He had been out of football since midway through the 2013 season, when he was suspended for being a central figure in a bullying scandal that led to offensive lineman Jonathan Martin leaving the Dolphins.

That news came the same day the Bills suspended their offensive line coach Aaron Kromer without pay for the first six games of the regular season for violating the NFL's personal conduct policy.

The action comes two days after prosecutors in Florida dropped a battery charge against Kromer for allegedly punching a boy in the face for using his beach chairs last month.

His suspension begins Sept. 7, in the week leading up to the Bills' regular-season opener against Indianapolis.

Seahawks, Wagner agree to a new deal

The Seattle Seahawks and Bobby Wagner finalized a four-year contract extension to keep the All-Pro middle linebacker with the club after this season.

Team owner Paul Allen confirmed Wagner's extension in a tweet late Saturday night. NFL.com first reported the deal and that it's worth $43 million, which would make Wagner the highest-paid middle linebacker.

Wagner finished second on the team with 104 tackles after missing five games last season because of a painful toe injury.

Cowboys camp skirmish

Dez Bryant and Dallas cornerback Tyler Patmon had to be separated in a heated exchange that lasted several minutes before Tony Romo stepped in and calmed his star receiver late in Sunday's practice.

Bryant, who has a history of sideline antics that include screaming at coaches and teammates, went after Patmon several times after the incident during 11-on-11 drills was over.

When practice ended a few minutes later, coach Jason Garrett spoke briefly to Bryant, who then walked over to Patmon and hugged him.

Bryant said he "got a little overheated."

Clowney nears return

Houston Texans coach Bill O'Brien's goal is to have outside linebacker Jadeveon Clowney (knee) practicing on Aug. 17. The 2014 No. 1 overall pick was placed on the physically unable to perform list just before camp began.
