Buffalo Bills LB Manny Lawson under investigation by NFL

The Buffalo Bills confirmed that linebacker Manny Lawson is the subject of a league investigation regarding a possible violation of the NFL's personal conduct policy.

The team released a statement two days after the Buffalo News reported that Lawson is being investigated by the league. Lawson on Wednesday told reporters that he was "shocked" to learn of the probe.

"We are aware of an investigation by the NFL under the Personal Conduct Policy but we have not heard from the league regarding the results," the Bills said in a statement.

Buffalo already has lost two players to suspension. Reserve running back Karlos Williams and defensive tackle Marcell Dareus will each miss the first four games of the season for violating the league's policy on substance abuse.

Lawson, entering his 11th season, is expected to start at outside linebacker while rookie Shaq Lawson recovers from injury.

"I don't know what's going on. I've reached out to the NFL," Manny Lawson told reporters Wednesday. "I've reached out to the organization and we're trying to get to the bottom of this."

The newspaper, citing sources, reported the veteran could be facing a one-game suspension. Manny Lawson has 24.5 sacks in 10 seasons with three teams, including the past three years with Buffalo.
