Abdallah (6-5, 300, 4.94) is ranked as the nation's No. 39 defensive tackle prospect by TheInsidersRecruiting.com. His host at OSU was Ashton Youboty.
"I really liked the people," Abdallah said. "Everybody was very cordial. They did a good job of making all of us feel wanted. Plus, I saw they have a great business school.
"You can really feel the tradition there. We got to see the stadium and it is real nice. Overall, it's just a great place."
Abdallah visited Colorado and Michigan State in December. He has trips remaining with Tennessee and Florida State the next two weekends.
"I'm definitely not going to say anybody is number one right now," he said. "But I would strongly consider Ohio State. I will wait and make my decision after I take all of my visits. I made a commitment to those schools to visit there and I'm going to."
OSU recruiting coordinator Bill Conley is Abdallah's primary recruiter, but defensive line coach Jim Heacock has also been involved.
"I got to spend some time with Coach Heacock," Abdallah said. "He's a smart guy. He's been coaching for like 25 years. He has a lot of experience and I know I can learn a lot from him.
"They are losing both of their starters at defensive tackle, but they brought in three guys at my position last year and redshirted them. Coach Heacock said if I come in and show what I'm all about, he will give me an opportunity to play. I am excited about that."
Abdallah, who participated in the U.S. Army All-American Bowl last weekend, had 76 tackles and 11 sacks for an 8-2 team as a senior despite missing three games due to injury.
He is qualified academically with a 3.0 GPA and a 19 on the ACT.
