"He obviously made a mistake and has paid dearly for that mistake; he continues to pay for that mistake," Pelini told reporters on Monday. "Our administration on the other side of campus kind of (said), 'these are the parameters you're going to have to abide by and do before we put you on scholarship and welcome you in."
Pelini wasn't part of the plan laid out by the school, but says Lewis has exceeded expectations off the field.
"He's done what he has to do away from football," said Pelini, who says academically Lewis is doing well.
The junior was a two-year letterwinner at Colorado, starting 12 games over his career. Lewis is currently getting first-team reps in spring practices and is expected to be a starter this fall.
