The senior tight end was involved in an accident over the weekend, and Seminoles coach Jimbo Fisher said O'Leary will miss the final six spring practices.
"He wrecked a motorcycle again," Fisher said. "He's skinned and got a swollen ankle and can't practice but he'll be fine. ... He's skinned from head to toe."
As a junior, O'Leary caught 33 passes for 557 yards and seven touchdowns and was named as a semifinalist for the John Mackey Award, given annually to college football's top tight end. He was also voted All-ACC Second Team. A three-year starter, O'Leary already holds the school record for touchdowns by a tight end (11).
With the departures of receivers Kelvin Benjamin and Kenny Shaw, O'Leary is expected to see an expanded role in the offense. Following Monday's scrimmage, which O'Leary did not participate in, Fisher pointed out the lack of production from his inexperienced receivers.
In May 2013, O'Leary was involved in a motorcycle accident but did not miss any practice time.
"He needs to be frustrated. It's not important if I'm frustrated. What's important is if he's frustrated and learned his lesson," Fisher said.
