An FBI affidavit alleges that Pilot Flying J — the country’s largest truck stop chain, owned by the family of new Cleveland Browns owner Jimmy Haslam —engaged in a fraud scheme aimed at keeping money owed as rebates to its customers.According to court documents, current and former employees of the company told authorities that Haslam, who bought the Browns last October for $1.05 billion, knew of the fraud and was present at meetings where it was discussed.The 120-page affidavit contends that the scheme was in place for five to seven years, that it targeted unsophisticated trucking companies, and that one company lost nearly $150,000 because of it.Haslam released a statement that said, “I’ve read the affidavits. I now understand more clearly the questions the federal investigators are exploring. ... We will continue to cooperate with the federal investigation and continue our own investigation in these allegations.”Briefly • Chiefs: Linebacker Orie Lemon, who was promoted from the Cowboys’ practice squad and played in five games for Dallas last season before injuring his hamstring, signed a one-year deal with Kansas City. • Falcons: Safety William Moore, who signed a five-year, $30 million deal last month, was arrested and booked into jail on a battery charge.
