Adam Schefter of ESPN had reported that Ryan was scheduled to have his second interview with Buffalo on Saturday night.
Ryan's first interview with the Bills was on Thursday. According to Schefter, the former New York Jets coach is the first of 12 known candidates for the job to interview twice with the Bills. The team has also reportedly requested interviews with New England Patriots offensive coordinator Josh McDaniels and Indianapolis Colts offensive coordinator Pep Hamilton.
The Bills' job opened up when Doug Marrone opted out of his contract last month following a 9-7 season. Buffalo still missed the postseason, as it has in every season since 1999.
Ryan was fired by the Jets last month after a 4-12 season kept New York out of the playoffs for the fourth straight season. In six seasons with the Jets, the 52-year-old went 46-50 with postseason berths in the first two (2009-10).
Ryan reportedly interviewed with the Atlanta Falcons on Wednesday, and also was expected to meet with executives at CBS about a possible broadcasting job should he not accept another head coaching job.
