NFL Line for Monday 7/17?

[Wheel Deal]

Sportsbetting.com has an NFL line for this Monday at noon between the Lions and the Broncos.....has to be a mistake in the date right?

07/17/06 3 Lions(Detroit) +290 +7.5 Over 46
13:05 ET 4 Broncos(Denver) -350 -7.5 Under 46

Yes, as the first preseason game isn't until August 6th

Denver plays Detroit on August 11th in the preseason
