"I'm fine," Griffin said Monday. "I'm up and going. I'm practicing."
Griffin leads the team with 86 tackles and tallied a season-best 16 stops against the Red Raiders.
"Just try to press on a broken toe," Co-Defensive Coordinator Gene Chizik said of Brown. "To be honest, we're hurt everywhere."
The only first-team Longhorns who have not missed a start this season are DE Tim Crowder, MLB Rashad Bobino and LCB Aaron Ross. Chizik was asked Monday if the injury situation in the secondary would prompt him to consider moving WLB Drew Kelson back to SS.
"I hardly have enough linebackers," Chizik said.
Senior SLB Robert Killebrew (knee) missed his first start of the season Saturday and is one of four Texas linebackers to miss entire ballgames in 2006. Meanwhile Kelson logged his first start of year at SAM after suffering a high ankle sprain just days before the home opener.
