As suspected, the game will be played at Floyd Casey Stadium in Waco on August 31, 2013. That means the Bears have 3 bye weeks during the season, including one right before conference play begins and one right in the middle.
Per David Smoak and John Werner on twitter, the recent conjecture about the September 14, 2013 game between SMU and Baylor has been true: the game will be canceled this season with the series restarting in 2014.
A rumor running rampant around the interwebs today has SMU looking to back out of the September 14 matchup this coming season. I'm not sure how much validity it has, but considering the late date, a cancellation would really suck for us.
