The NFL has determined the Buffalo Bills acted properly in the aftermath of team president Russ Brandon's resignation amid allegations he had an inappropriate relationship with a female employee.

The league released a statement Friday saying it will take no further action against the Bills. The league determined the team "addressed the matter in a timely Lorenzo Alexander Jersey , thorough and appropriate manner."

The statement comes a week after the NFL wouldn't rule out launching an investigation in announcing it planned to contact the Bills to discuss the reasons behind Brandon's abrupt departure.

Brandon resigned May 1 after spending 20 years working up the Bills' executive ranks. He also spent the past three years serving as president of the NHL's Buffalo Sabres, who also are owned by Terry and Kim Pegula.

Two people with direct knowledge of the situation told The Associated Press that Brandon's resignation came after he was confronted about the relationship by the Pegulas. The people spoke on condition of anonymity because it is an internal matter, and the Pegulas did not provide a reason when announcing they accepted Brandon's resignation.

Brandon told the AP he had contemplated stepping down from the job for some time Robert Newhouse Jersey , and felt the timing was right following the conclusion of the NFL draft. He did not respond to follow-up questions regarding the alleged relationship.

The NHL last week consulted with the Sabres and determined Brandon's resignation was a club matter.

Former Miami Dolphins offensive lineman Jonathan Martin was charged Tuesday with threatening two former teammates who had harassed him in the NFL and with threatening his former prep school classmates, Los Angeles County prosecutors said.

Martin pleaded not guilty to four felony counts of making criminal threats and a misdemeanor charge of carrying a loaded firearm, district attorney's office spokesman Greg Risling said.

A post on Martin's Instagram page last month showed a shotgun and referred by name to the private Harvard-Westlake prep school in Los Angeles that he once attended.

The post also included mentions of the Instagram usernames of former Miami Dolphins players Richie Incognito and Mike Pouncey and said suicide and revenge were the only options for a victim of bullying.

Martin left the Dolphins midseason in 2013 after accusing teammates of bullying. An NFL investigation found that Incognito Bob Lilly Jersey , Pouncey and teammate John Jerry engaged in persistent harassment directed at Martin.

Incognito was suspended for the final eight games and sat out the 2014 season before joining the Buffalo Bills.

Pouncey was released by Miami last week and agreed to a two-year contract Monday with the Los Angeles Chargers

The NFL's investigation also found that teammates threatened to rape Martin's sister, called him a long list of slurs and bullied him for not being "black enough." Martin is black and Incognito is white.

Court documents say Martin "did willfully and unlawfully threaten to commit a crime which would result in death and great bodily injury" of Pouncey and Incognito. Both Pouncey and Incognito feared for their own safety and the safety of their families, the documents said.

Prosecutors said Martin also had a loaded firearm in his vehicle in Glendale Marcus Cooper Jersey , but court papers provided no other details.

The name of Martin's attorney was not immediately known. Prosecutors said he is due back in court next month and faces up to six years in prison if he's convicted.
