As the Tarblooders were earning a 51-12 victory against John F. Kennedy, Walker watched from the sidelines after having suffered a knee injury during practice the week before that has him out of action for an indefinite period of time.
"I was blocking and the running back ran into my knee and it popped," he told BuckeyeSports.com while standing on Roye Kidd Field following his team's win. "I don't actually know (when I'll be back), but I'll be all right. I have to go see a sports medicine doctor and see what's wrong but other than that I'm just working to get back on the field and help my team."
Although the Tarblooders were able to carve out a lopsided victory, head coach Ted Ginn Sr. said Walker's absence had an effect on his team.
"I think we lose a little something because kids like certain people next to them," he said. "Kids are going to be a little down and slow. They've been used to Aundrey being in the game and he wasn't in the game. They might be a little sluggish."
Walker said it was the first game he had ever missed.
"It was sad, but at the same time I want my team to win and me being sad might bring down another player so I have to build everybody up," he said.
As a sophomore, Walker said he injured his other knee.
"I got cut blocked (that year) and it popped to the left," he said. "I sprained my MCL but I'm cool though."
The lineman was set to see another doctor Oct. 4.
"You're always concerned when a kid is injured," Ginn said. "You always try to teach them to protect themselves and stay focused and play hard. A lot of times they like to plays off and sometimes things happen."
Scout ranks Walker the No. 12 offensive guard in the nation. He is receiving interest from a number of colleges across the country, but Walker has declined to eliminate schools from his list because he considers each opportunity a blessing.
"Once it comes down to (picking the) school, as a man and out of respect I'm going to call those college coaches and say, ‘Thank you sir. I appreciate you taking the time to recruit me but I don't feel that your school is for me,' " he said. "I hope they respect that."
Although he remains focused on his senior season and his teammates, Walker said he knows the destinations for three official visits he will take after Thanksgiving: USC, Michigan State and Ohio State.
Walker said he receives daily phone calls from a number of colleges. When the Buckeyes call, "We talk about life and how I'm doing and all that. Just the whole recruiting process."
JFK offensive guard Chris Carter said he has spent a little bit of time trying to recruit Walker to join him as an OSU verbal commitment.
As one of four Glenville seniors projected as Division I talent, Walker has been mentioned as being part of a package deal along with wideout/return specialist Shane Wynn, quarterback Cardale Jones and defensive end Andre Sturdivant.
Asked if the four will continue to bill themselves as a package deal, Walker said, "We have talked about it but we don't know. We'll see."
For now, the focus is on trying to get his team a few championships once he returns to health. Last season, the Tarblooders dropped a 16-15 decision to Hilliard (Ohio) Davidson in the state title game.
"It dogs us every now and then," he said. "That's what we're striving for and that's what motivated us to go to the state championship and win it all. We don't just want to be state champions but be national champions, undefeated at 15-0."
