Bills busy as free agency begins Tuesday afternoon

The Buffalo Bills have been one of the NFL's most active teams this offseason, and as the NFL's free-agent signing period is set to open Tuesday at 4 p.m., they remain one of the league's most talked-about teams.

Here is a roundup of the latest reports from around the Web:

RB Bilal Powell: The Buffalo Bills had interest in signing Powell, a source told ESPN's Dan Graziano on Sunday, but Powell has re-signed with the New York Jets, ESPN New York Jets reporter Rich Cimini confirmed Tuesday.

S Da'Norris Searcy: Considered one of the top free-agent safeties on the market, Searcy is "poised to sign" with the Tennessee Titans, The Tennessean's Jim Wyatt reported Tuesday afternoon. The Bills weren't expected to re-sign Searcy after giving Aaron Williams a large extension last season. Several other teams were reported to have interest in Searcy.

OT Bryan Bulaga: The Bills will have both of their starting offensive tackles from last season, Cordy Glenn and Seantrel Henderson, back next season, but that doesn't mean they aren't looking to upgrade. The Buffalo News' Tim Graham reported Monday that the Bills have interest in signing former Green Bay Packers tackle Bryan Bulaga, considered the top free-agent option at his position. However, NFL Network's Ian Rapoport reported Tuesday afternoon that the Packers were expected to keep Bulaga and were "closing in on a deal."

TE Charles Clay: The Miami Dolphins assigned Clay the transition tag, but that might not stop the Bills from pursuing him. The South Florida Sun Sentinel's Omar Kelly reported Sunday that the Bills are expected to make Clay "a substantial" offer, a report echoed by CBS Sports' Jason La Canfora on Tuesday. The Dolphins would have a week to match the offer, and if they don't, they would receive no compensation from the Bills for Clay.

FB Jerome Felton: Bills general manager Doug Whaley said at the NFL combine that he expects the Bills to add a fullback this offseason. It could be former Minnesota Vikings fullback Felton. La Canfora reports that the Bills "hope" to sign Felton.

WR Percy Harvin: The New York Daily News' Manish Mehta reported Tuesday morning that the Jets will release Harvin on Tuesday. There haven't been any reports directly tying Harvin to the Bills, but it wouldn't be surprising if interest emerges. The Bills could use a third receiver behind Sammy Watkins and Robert Woods, and Harvin played for Rex Ryan with the Jets last season. ESPN NFL Insider Adam Schefter reported Friday that the Bills had some level of talks with the Chicago Bears about Brandon Marshall before he was traded to the New York Jets.

CB Darrelle Revis: It appeared earlier this offseason that the Bills would have interest in Revis, should he become available. That's expected to happen Tuesday, but the Bills aren't expected to be in the running. Rapoport reported Tuesday morning that the Jets, New England Patriots, Cleveland Browns, Oakland Raiders and Kansas City Chiefs will all be vying for Revis' services.

G Mike Iupati: The former San Francisco 49ers guard Mike Iupati has told people that he plans to sign with the Arizona Cardinals, a source told Schefter. La Canfora reported Sunday and Fox Sports' Ross Jones reported Monday that the Bills were in the hunt for Iupati -- considered the top free-agent guard -- but the Buffalo News' Vic Carucci reported Monday evening that the Bills weren't pursuing Iupati.

K Jordan Gay: The Bills and Gay agreed to an undisclosed contract extension Monday, the team announced. Gay was an exclusive-rights free agent and had no choice but to remain with the Bills if they wanted him, which they clearly did. Gay served as the Bills' kickoff specialist last season.

WR Marcus Easley: The Bills' top special-teams player the past two seasons is expected to have interest from several teams, but the Bills are looking to retain him.

TE Lee Smith: Another unrestricted free agent set to hit the open market, Smith is "expected to sign a big contract with another team" on Tuesday, Graham reported Monday evening.

QB Matt Cassel: The Bills' trade for Cassel will be made official Tuesday, but that might not be the end of the story. Rapoport reported Sunday that the Bills could give Cassel a multiyear extension. As it stands, Cassel is under contract only through 2015, with a $500,000 roster bonus due this weekend. He has a $4.75-million cap number that can be lowered if the Bills convert part of his base salary ($4.15 million) to a signing bonus and extend the deal, which would prorate the signing bonus over the length of the contract.
