STILLWATER, Okla. -- Nervous moments for Oklahoma State may have ended.

The offense had been stymied for five consecutive drives, including Brandon Weeden's first interception of the night that stuck Arizona deep in its own territory.

But after a three-and-out gave Oklahoma State the ball back in Arizona territory, the offense got back on track.

Predictably, with Weeden to the nation's top receiver, Justin Blackmon, who finished the drive with a perfect catch on the back half of a fade route for the second time on Thursday night.

Oklahoma State leads, 27-7, entering the fourth quarter.

Blackmon caught passes on four consecutive plays, stretching his streak of 100-yard games to 13. He's got 11 catches for 125 yards and two touchdowns.

The touchdown pass also gave Weeden the school record for completions in a game, with 35.

Additionally, linebacker Alex Elkins was cleared to return after his injury and is back on the field.
