The NFL will release its schedule at 7 p.m. Tuesday.
The Bills' series in Toronto has been a yawner for Canadian fans. Seats have been difficult to fill and electricity tough to generate in a venue that has felt more like a mausoleum. The NFL has tried to help create local interest by constantly tinkering with kinds of opponents and dates.
When the first meaningful game took place in December 2008, Bills fans were upset about forfeiting a cold-weather game to the Miami Dolphins while the Bills still were alive for a playoff bid.
The NFL tried a Thursday night game against the New York Jets in 2009, but the idea of a prime-time game didn't make much difference. A nonconference opponent was tried last year with Chicago.
Buffalo is 0-3 in regular-season Toronto games, but 2-0 in the preseason exhibitions there.
