"I didn't go," Walker said. "They canceled my flight because Coach Jones took the job at Tennessee. I gotta see what's up now."
Walker, 6-foot-2 and 190 pounds, said three other schools have also jumped in the mix lately.
Walker now has a single favorite, especially after Jones left Cincinnati.
"Nebraska is probably my favorite right now. I really like their program and they're coaching staff," he said. "I haven't scheduled any other visits yet but I hope to soon."
The standout receiver, who says he's unsure about his in-home visit schedule with coaches this week, would like to take a few more trips before making a final decision.
