NORMAN — Mike Balogun’s future on the playing field at Oklahoma is in jeopardy. The NCAA has ruled Balogun ineligible while it investigates whether the senior middle linebacker participated in semi-pro football after his 21st birthday. Per NCAA rules, a player loses a season of collegiate eligibility for each semi-pro season he plays past the age of 21. Balogun, 25, is being allowed to practice with the team for now; however, after Wednesday it is uncertain whether that will be allowed to continue. After high school, Balogun, who didn’t play football his last two years of high school, joined the Maryland Marauders, a semi-pro team. The next season, he played for the Prince George Jets. Balogun eventually earned a scholarship to Lackawanna (Pa.) Community College. After two years there, Balogun was signed by the Sooners in 2008. Before his arrival at OU, the NCAA interviewed Balogun about his semi-pro past, then certified his eligibility in May 2008, Sooner officials said. OU’s compliance office subsequently confirmed Balogun’s eligibility after the NCAA did. However, according to OU officials, "more information came to light” after last season regarding when Balogun played semi-pro football. OU’s compliance office passed along its finding to the NCAA. "I don’t know how we could have done more than we have in this matter, and we’ve had a good working relationship with the NCAA on Mike’s case all along,” coach Bob Stoops said. "We’re still hopeful that Mike will be eligible for this season, but we’ll have to see what happens over the coming days.” Both Stoops and OU spokesman Kenny Mossman said after practice Friday they don’t believe the Sooners will be penalized by having to forfeit any of the 10 games Balogun played in last season. "I think, from what I understand, precedent is not to take wins away,” Stoops said. Balgoun could still rejoin the team if the NCAA reinstates him. But with Balogun’s status currently tenuous, true freshman Tom Wort should see more practice time as a backup to starter Ryan Reynolds at middle linebacker. Sophomore Austin Box, who has been working this preseason at weak-side linebacker behind Travis Lewis, started four games last year at middle linebacker and could be moved back there if needed.
