The Buffalo Bills are expected to announce they will not play a game in Toronto this season and have all eight of their 2014 home regular-season games in Orchard Park.

The Bills were working diligently the past week with their Toronto series partner, Rogers Media Inc., to move this season’s Toronto game back to Ralph Wilson Stadium, a source connected to the series told The News. It was not clear what the move would mean for future years of the Bills in Toronto series. It’s possible the Bills could be calling a one-year hiatus in the series.

Buffalo has played a regular-season game in Toronto’s Rogers Centre each of the past six years. The Bills began a five-year partnership with Rogers, the Canadian telecommunications giant, starting in 2008. They extended that deal for five more years starting in 2013 and running through 2017.

The Bills have yet to create a strong, home-field environment for the games in Toronto. Last year’s game drew an announced crowd of 38, 969, at least 12,000 short of a sellout. The Bills lost an overtime decision to the Atlanta Falcons, 34-31. The atmosphere arguably was the worst yet from the Buffalo perspective in the Toronto dome, with almost as many fans rooting for the Falcons as the Bills.

Russ Brandon, Bills president and chief executive officer, was non-committal about the future of the series in the weeks after that game, which was played on Dec. 1.
