At the combine in San Antonio, Walker listed a number of schools that he thought he had offers from, but this was not the case.
"I don't have any offers right now," Walker said. "I made a mistake. I thought I had some, but I didn't."
Walker may not have received his first offer, but he is still drawing interest from some of the top programs from around the nation.
"I'm hearing a lot from Texas A&M. Oklahoma and Oklahoma State have started showing a lot of interest. The Florida Gators are coming on strong, and Cal has started sending letters and talking to me," Walker said.
"Texas A&M is my top school right now," Walker added. "I like the school and the way everything goes down there. Everything is really nice. Their school just fits me well. I don't want to go far from home."
Many people thing that the 6-foot-7, 245-pound Walker would be better suited to play basketball on the next level. Walker is also being recruited to play both sports by A&M and talked about which sport he would rather play on the next level.
"I'm not sure if I am going to get any taller, but I will probably play basketball if I grow above 6-foot-10," Walker said.
Walker recorded 61 tackles and one sack during his junior season at Antonian College Preparatory High School.
