Wes Lunt went down in a heap, and the folks in orange couldn't do much besides look (or look away), hope and pray.
On the opening drive of Oklahoma State's 65-24 win over Louisiana, Lunt was brought down by a defender and immediately clutched his left knee.
Trainers tended to him for several minutes, and sideline reports (and photos from the game) indicated the injury was a dislocated kneecap.
That was ugly, and it had Oklahoma State fans sweating through the fourth quarter of a game that was never in doubt.
What wasn't ugly? The reason why the game wasn't in doubt: backup quarterback J.W. Walsh. Lunt narrowly beat out Walsh to win the job this spring, but Walsh stepped in and proved he was capable -- albeit against a weaker opponent than he'll see in the Big 12 -- for the rest of the game.
Lunt was injured on the first drive, but Walsh engineered scores on his first eight drives, helping OSU jump out to a 44-0 lead at halftime.
Walsh finished with an eye-popping stat line: 20-of-29 for 341 yards, four touchdowns and no picks. On the ground, he added 73 yards and a touchdown on six carries.
Louisiana's not a great team, but the Ragin' Cajuns had given the Cowboys trouble in the past, picking off Brandon Weeden for touchdowns twice a year ago and leading at halftime in a game down in Lafayette back in 2010. This was nothing like those games.
Oklahoma State fans have reason to worry about Lunt, but for now it's hard not to be encouraged by what Walsh showed on Saturday.
Texas in two weeks will be a much different challenge for Walsh (or whoever quarterbacks the Cowboys), but on Saturday, he did everything he could to convince the Cowboys faithful that he'll be ready.
