Did Cowboys use their challenge in first half?
I missed the first 20 minutes of the Cowboys game... did they lose their challenge during that time, since they did not challenge the obvious 'knee down' on the kick-off, just before the half?
Or could they not use it since they were out of time outs?
That was such an obvious call, though... even in real-time the guy was obviously down. Not that the Packers needed the extra 7 points anyway.
