Baylor junior defensive end Xavier Jones could miss the rest of the season after breaking a bone in his leg in Saturday’s 49-41 loss to Oklahoma.

Baylor coach Matt Rhule said wide receiver Chris Platt is undergoing tests to determine the extent of a knee injury that forced him to go out in the second half of the game. However, offensive tackle Mo Porter is expected to play in Saturday’s game against Kansas State in Manhattan after going out with an injury early against the Sooners.

With Jones out, defensive ends Brian Nance, Greg Roberts, Deonte Williams and Jamie Jacobs will be counted on more heavily to carry the load. Jones had six tackles through Baylor’s first four games, including two for loss and 1½ quarterback sacks.

Rhule was pleased with his team’s effort against the No. 3 Sooners, but is looking for more improvement as the Bears prepare for a tough environment at Kansas State.

“I’m definitely proud of how far they’ve come,” Rhule said. “They’re playing more and more winning football. I liked the way that they didn’t get down on themselves. We showed toughness in the fourth quarter, and I’m proud of the way they fought back, but we have to get better in a lot of areas.”
