Freshman Matt Romar was one of the freshmen the Sooners were expecting to play this season.
But Romar didn't dress, instead coming out on the field with a brace on his right leg and a wrap under the brace.
Several other freshmen, though, made their OU debuts — outside of Knight.
Ahmad Thomas, Jordan Evans and redshirt Derrick Woods all played on the kick return team to start the game.
Sixteen players made their Sooner debuts, including running backs Keith Ford and Alex Ross.
Ross drew an unsportsmanlike conduct penalty after his lone carry.
FORMER PLAYERS RETURN
With the NFL season not starting for another week, a couple of former Sooners now playing professionally used the time to return to Norman.
Detroit Lions receiver Ryan Broyles watched the game from the sidelines, as did Tony Jefferson and David King.
Jefferson went undrafted after entering the draft following his junior year last season but signed with the Arizona Cardinals.
Jefferson made the Cardinals roster, while King was among the last cuts for Philadelphia.
SELLOUT STREAK CONTINUES
There were still tickets available as of late Friday evening but the sellout streak that stretches the entirety of the Bob Stoops era lives on.
The announced attendance was 84,911 — nearly 3,000 above the listed capacity of 82,112.
SEVERAL IN-STATE RECRUITS WATCH GAME
The list of visitors for Saturday night's game wasn't very long but included several commits.
Edmond Santa Fe quarterback Justice Hansen, Tulsa Union tight end Carson Meier, Irving (Texas) Ranchview defensive end Brandon Glenn and Casady offensive lineman Josh Wariboko-Alali (2015) were expected to visit for the game.
Among the other in-state players expected to be in attendance were Lawton offensive guard Jalin Barnett, Guthrie athlete Kai Callins and Jenks defensive back Steven Parker.
Barnett and Parker have Sooners offers.
