Missouri nearly failed to get a timeout in at the end of the first half. It would have cost the Tigers three points.
An effective drive got Missouri into field goal range, but the Tigers stalled just before the Oklahoma red zone, then called a run to get a better shot for Grant Ressel. That was almost a big mistake: Missouri only got its final timeout called with one second remaining.
Ressel drilled the 31-yarder after that, but the Tigers are living on the razor's edge against Oklahoma, and should the Sooners clean up their turnover issues and convert all of their red zone trips to points, the Tigers might have trouble keeping up.
And they may be losing the lead shortly, in any case: Oklahoma will receive the ball to begin the second half.
