KANSAS CITY, Mo. -- It hasn't been the smoothest of starts for Oklahoma so far.
But even after losing starting tailback DeMarco Murray on the opening kickoff and having the Sooner Schooner damage a wheel after its first touchdown, Oklahoma is cruising with a 10-0 lead over Missouri after the first quarter.
Murray hobbled off with what appeared to be an ankle injury on the opening kickoff. He hasn't played since, but hasn't been missed as Chris Brown has rushed for 44 yards on eight carries and a touchdown.
Sam Bradford has showed little effect of his thumb injury, passing for 96 yards. The Sooners have used the shotgun, an easier snap to handle, almost exclusively.
Oklahoma has played several snaps at the end of the first quarter in a defensive formation featuring two down linemen. The first play resulted in a loss and the second was a 15-yard gain from Chase Daniel to Tommy Saunders -- the Tigers' longest gain of the first quarter.
The Sooners have attacked Missouri early with a fierce defensive performance so far, limiting the potent Missouri offense to only 49 yards and 3.1 yards per snap.
The Oklahoma defense turned away the Tigers on two possessions inside their own 40. Jeff Wolfert missed a field goal on the Tigers' first possession and a devastating hit by Keenan Clayton on Daniel killed the Tigers' drive after Missouri had taken over at the Oklahoma 41.
