Anderson said he and two of his teammates will sign letters of intent during the ceremony.
"I have not really narrowed it down any more," Anderson said. "I have no idea who would be the leader right now. I don't know. I'm taking as much time as I can. It'll be really hard to narrow it down. I can't lose with any of these schools. They are all great programs and I don't know who I'll choose.
"I spent some time talking with coaches from all four of those schools and just wrapping it up. I have three (letters of intent) so far and I expect one from USC, too."
Anderson said OSU linebackers coach Luke Fickell made one final pass through his hometown on Thursday.
"I saw Coach Fickell on Thursday," Anderson said. "He talked with my mom and we played Madden. He beat me one game and I won the other, so we're tied."
Anderson is ranked as the nation's 12th-best defensive end in the country and as the nation's 98th-best prospect overall by TheInsidersRecruiting.com.
He tallied 38 sacks over the last two seasons at Oak Creek.
He holds a 2.6 GPA and scored a 19 on the ACT.
