Robinson was one of the most effective quarterbacks in school history, but was also beaten, battered and a shell of his former self by the end of his career.
BYU sophomore quarterback Taysom Hill torched the Texas defense for 259 rushing yards in last week's upset, but his 2012 season ended in early October after taking a helmet directly to his knee.
Nebraska quarterback Taylor Martinez left the Cornhuskers' season-opening win over Wyoming with a shoulder injury after an early third-quarter run.
“We try to do a really good job of educating and letting our quarterbacks understand that they can't take hits,” said OU co-offensive coordinator Josh Heupel. “(Knight) took one that caught up with him.”
Knight, Bell and sophomore Kendal Thompson battled in an intense quarterback competition through the spring and summer. A foot injury in early August cost Thompson a chance to start the opener, but he returned to practice this week and will be available Saturday against Tulsa.
“I've said this from the very beginning to all those guys — the strength of that position is going to have to be the group,” Heupel said. “I would say that every year, but it's certainly true this year with an injury.”
