The Buffalo Bills worked out veteran free agent kicker Billy Cundiff on Monday, a source told ESPN's Jeremy Fowler.
The Bills also worked out free agent kicker Alex Henery on Monday, a source told ESPN NFL Insider Field Yates.
Coach Rex Ryan expressed frustration last week about Bills kicker Dan Carpenter, who missed three field goals and one extra point in three preseason games.
"You know I’m concerned," Ryan said Friday, "and I’ll tell you the reason I’m concerned about it is [that] going into the year, I thought we had everything nailed there. I thought that ‘Hey look, we’ve got a kickoff guy, we’ve got a kicker, we’ve got a punter, we’ve got a long-snapper.’ You know you feel great about this and really we weren’t looking for anything.
"But to say that I’m just going to turn a blind eye to the fact that we missed four kicks, that’s not me. You can criticize me all you want about it, but I could care less. I’m about right now, about this team and if there’s somebody that we feel can help our team, regardless of the position, then we’ll certainly look at it."
Carpenter understood Ryan's frustration when speaking to reporters in the locker room Friday.
"If you have a kicker who goes 3-for-6 in the preseason, that should [make you] concerned as a coach," Carpenter said. "That's their job. Obviously I need to do better. I know that. He's knows that. Everyone else in this building knows that, and everyone else in this building expects me to do better."
There are reasons to pump the brakes about Carpenter's preseason struggles. One of his misses was a difficult 53-yard field goal and Carpenter did not participate in offseason workouts or the first two weeks of training camp because of an undisclosed injury.
Carpenter also has been one of the NFL's more accurate kickers, with his 90.5 percent field goal conversion rate the league's fifth-best since the start of the 2013 season.
"You always factor it, look I know the history," Ryan said Friday. "This guy’s been a clutch kicker for many years, and kicking here, not all kickers can kick in this condition so I recognize that. But I’m also not blind and obviously he had some issues, but how he responds now ... I think the important thing is right now, what’s important now.
"We’re in the win business, what’s important now and if he’s the best kicker, we think he’s the best kicker, he’ll still be here. That goes for any position. If there’s somebody that we feel is better, then that person will be here."
Carpenter struggled on kickoffs in the 2013 season, leading the Bills to carry Jordan Gay as a kickoff specialist last season and again on their 53-man roster this season, which was finalized this weekend. The Bills could consider the option of signing a new kicker appealing because it would allow them to release both Carpenter and Gay, opening a roster spot to be used for another position.
The Bills also could save $1.2 million off their 2015 salary cap by releasing Carpenter this week.
