ACL tears are painful and can force players to miss whole seasons. A lot of players think they are a big deal, but not Corey Lewis.
Lewis, an offensive lineman with Illinois University played the entire 2013 season with an ACL tear according to reports.
Offensive tackle, Lewis has torn the ligament four times in his career and when he felt a problem during pre-season training, he just ignored it.
"I felt that if I could play, there was no reason to MRI it and get shut down if something came out of the MRI," said Lewis. "I just wanted to play my last season."
After two successful years with the Fighting Illini, during which he was awarded All-Big 10 academic honors, Lewis missed two and a half seasons with his knee problems.
He went through five surgeries in order to return for this season and help out his teammates.
Lewis' knee damage could put pay to a professional career, but he will be attending a pro day this year to lift weights and potentially be drafted by an NFL team.
If he is unsuccessful, Lewis already has a Masters degree and ambitions of being an Athletic Director one day.
