Per Mike Florio of Pro Football Talk, Horton will sit down with Bills brass - a group including Russ Brandon, Buddy Nix, Doug Whaley and Jim Overdorf - on Wednesday evening to interview for the position vacated by the fired Chan Gailey. That will be Horton's second interview of the day, as Florio also reports that Horton will interview for Arizona's opening for the second time on Wednesday, as well.
A hot commodity at the moment, Horton also interviewed with the Cleveland Browns on Tuesday for their job opening, per the PFT report.
Horton, 52, is a former NFL defensive back that came to Arizona after spending time working as the Pittsburgh Steelers' defensive backs coach. A self-described "Dick LeBeau devotee," Horton's Cardinals defenses finished No. 14 and No. 12 in his two years on the job, racking up some huge statistics in the process - including 112 sacks, 44 interceptions, 22 fumble recoveries, four safeties and nine total touchdowns.
Buffalo has already interviewed Horton's former boss, Ken Whisenhunt, for its head coaching job, as well.
