All tests came back negative and Guerrero was released Tuesday afternoon. He is expected to make a full recovery.
Guerrero, a Bellflower, Calif., native went to St. John Bosco High School where he was a member of the Los Angeles Times' 10-member All-Star team and he was the co-MVP of the Trinity League in Southern California.
He averaged more than 28 point per game as a senior but is best known for his elite ball handling and passing ability.
Perhaps his best high school performance came when he poured 48 points on nationally recognized Mater Dei, who finished as the No. 11 team in the country last season.
He came to OSU as a four-star prospect and was rated as highly as the No. 61 overall player in the country.
Coach Travis Ford has been very high on Guerrero's development through individual workouts. This is what Ford had to say about Guerrero last week.
"C.J. has picked things up as fast as anyone I've coached in a very, very long time," Ford said. "All the coaches have been impressed with him and how he's prepared. He's also one of the tougher kids; he's not backed down from anybody in any of the drills. He's going right at Keiton (Page), right at Reger (Dowell) and right at the rest of the guys. He doesn't back down. To that extent, he's been impressive. He just has to learn what he can and can't do at this level. He's got to simplify things a little bit … he likes to penetrate too far at this point but that's all part of the process of learning. For what we thought we were bringing in — a guy that could really handle the ball and pass and shoot — he can do all three of those with some toughness to him. It's been exciting to see."
Despite a scary moment yesterday, OSU took all the necessary precautions and the program was excited to announce that they expect him to make a full recovery and will be able to rejoin the team in the near future.
