"I'll be coming in this weekend," said the three-star defensive tackle from Garland (Texas) High School. "I'll be there Friday to watch them practice. I'm pretty excited about it."
Walker said four-star safety and fellow Sooner commit Joseph Ibiloye of Garland South will also be making the trip with him.
Walker, who said he's made a handful of unofficial visits, hasn't been in Norman since the Sooners hosted Miami (Fla.) earlier this fall.
"I'm just looking to get a tour around Oklahoma (campus)," he said. "I want to see what's out there."
Walker said he still receives a few calls from other suitors, but they've mostly died down since he made his commitment. It's a commitment, he said, that's solid.
"OU is my final and that's it," he said.
