Three initial bids were submitted Tuesday to an investment bank handling the sale of the Bills, the Toronto Sun reported.
Terry Pegula, owner of the NHL's Sabres; a Toronto-based group that includes rock star Jon Bon Jovi, and real estate developer Donald Trump submitted bids, the report said.
The New York Post reported Pegula's bid topped $1 billion.
It's possible a prospective owner could be identified by late August and presented to NFL owners for approval during league meetings in early October.
Trump confirmed his bid Monday in an interview with Fox News but said it was "very, very unlikely" he would own the team.
In other Bills news Wednesday, running back Fred Jackson signed a one-year contract extension and linebacker Nigel Bradham was suspended by the NFL for the team's regular-season opener for violating the league's substance abuse policy.
bengals: Cornerback Chris Lewis-Harris was suspended for two games for violating the NFL's substance abuse policy.
cardinals: Patrick Peterson is the highest-paid cornerback in the NFL. Just ask him. Not only did he put on Twitter the terms of his new contract — five years, $70 million, $48 million guaranteed — he referred to himself as the highest-paid at his position at least five times in the news conference announcing the new deal, twice before he was asked a question. Peterson, 24, is the first of the 2011 draft class to sign a second contract. The fifth overall pick out of LSU had two years left on his previous deal after the Cardinals picked up his fifth-year option. He and Seattle's Richard Sherman have carried on a Twitter rivalry. Sherman signed a four-year, $56 million contract — $40 million guaranteed — this year. "I don't have any beef with Richard," Peterson said at the news conference. "I'm having fun. I don't know if he's having fun, but I think it's going to make me take my game to the next level." He noted some of Sherman's Twitter posts are "a little salty." "I guess it will be must-watch TV when we play Seattle."
Cowboys: Rookie defensive end DeMarcus Lawrence will miss at least two months after breaking his right foot. Tyron Smith was signed to an eight-year extension that locks up the left tackle through 2023. The extension is worth $98 million, pushing the total value of his deal to 10 years and $110 million. He gets a $10 million signing bonus and $40 million in guaranteed money. Smith was just 20 when the Cowboys took him ninth overall in 2011 out of Southern California.
dolphins: Players, rocked by a bullying scandal last season, are wearing T-shirts bearing a credo of togetherness that was coined by them. On the back is a list of 10 sayings bordered by the words "I am a Miami Dolphin" that encompass their approach to the upcoming season. Among the sayings that bring to mind last year's scandal involving former offensive linemen Richie Incognito and Jonathan Martin is: "If I see something — I will say something — I commit to call it as it is."
Steelers: The team will retire Hall of Fame defensive end Joe Greene's No. 75 during a game Nov. 2 against the Ravens. "I'm overwhelmed with emotions, for sure," he said in a statement. "That was my first thought. I was just very, very surprised, and I almost fell out of my seat." No Steeler has worn No. 75 since he retired in 1981. He is the second player to have his number retired. Pittsburgh retired Hall of Fame defensive lineman Ernie Stautner's No. 70 in 1964.
