Starting safety Supo Sanni has been lost for the season with a torn Achilles tendon, Illinois coach Ron Zook said today.
The injury was suffered during Wednesday's practice. Sanni will have surgery today.
"I feel bad for him, but he'll be all right," Zook said.
Sanni hasn't redshirted and will have two years of eligibility remaining.
Trulon Henry and Travon Bellamy are now the starters at safety. Bellamy had been contending for a starting spot.
To help with depth in the secondary, Justin Green has been moved from running back to cornerback.
"The last couple days, he's really looked good," Zook said. "He's been very, very impressive."
Receiver Steve Hull is likely to be tried at safety, Zook said.
