"I've never said that," Gailey said.
Hangartner wasn't available for comment. His agent, Eric Metz, declined comment except to say, "After 27 years of this, it's all about actions, not words."
The move was considered a surprise, especially after both Gailey and general manager Buddy Nix expressed concern about the line's lack of experience during training camp.
Hangartner was the Bills' most experienced and highest-paid lineman. He was scheduled to make $2.55 million this year and $5.35 million in base salary over the final two years of his contract.
"Each individual decision is on its own merits," Gailey said. He added that the moves were made based on "knowledge, insight and opinion and what we feel is best for the opportunity to beat Kansas City and for the future of our football team."
Those moves leave the team with three tackles, including fourth-round pick Chris Hairston, who's currently serving as the lone backup. Starting guard Andy Levitre also has experience playing the position.
Wang made headlines in becoming the first player with direct Chinese ancestry to be selected in the NFL draft last year, when the Bills chose him in the fifth round out of Virginia Tech. He missed much of last season with a thumb injury, then was sidelined for part of training camp last month with a shoulder injury.
Third-year safety Jon Corto (shoulder) also was waived/injured, and running back Bruce Hall was placed on season-ending injured reserve.
Davis was beaten out by Ruvell Martin, a fifth-year pro who had signed with the Bills 10 days earlier.
"First of all, he did a great job of picking up the offense quickly," Gailey said of Martin. "And he played well on special teams. It was a good combination to have coming in on short notice."
Also cut was rookie defensive tackle Michael Jasper. At 6-foot-4 and 383 pounds, Jasper was considered a project after being selected with the second of the team's two seventh-round picks out of Bethel University.
Gailey described Jasper as "a viable candidate" to be placed on the Bills' practice squad should he go unclaimed on waivers.
Second-year tight end Shawn Nelson also was cut in a move that didn't come as a surprise. He has been hampered by an assortment of injuries and opened last season missing the first four games while serving an NFL-imposed suspension for violating the league's substance-abuse policy. He appeared in just five games last season before being placed on the reserve/injured non-football injury list as a result of migraines.
A fourth-round pick out of Southern Mississippi, Nelson then missed most of training camp last month with a leg injury.
