"Went really well," Stoops said. "Everything went just as expected. No surprises. Both are healing really well."
And both will still miss the rest of the season following their Tuesday procedures. Nelson, a team captain at linebacker, had surgery for a partially torn pectoral muscle. Phillips, who had been emerging as a star at defensive tackle, had back surgery.
It's something Stoops has heard for years himself, and he said he supports Heupel and has no problems with the direction of the program.
"That's part of the job," Stoops said. "You throw it on third-and-short and score a touchdown, you're a genius. If you throw it on third-and-short and it's incomplete, you're a knucklehead. Everybody thinks they know.
"They're big boys. You don't realize how little we hear. We're in our deal working. We don't really care what has to be said. We're in our caves getting ready for practice and trying to get better."
Stoops said he's happy with the way his team has responded in the first three practices since the loss to the Longhorns and said the goal of winning the Big 12 championship remains attainable.
