BATON ROUGE, La. (AP) -- LSU assistant coach Steve Kragthorpe has been diagnosed with Parkinson's disease and is relinquishing his duties as offensive coordinator, but is remaining on the Tigers' staff.
Kragthorpe, who was hired during the offseason, will remain as the quarterbacks' coach while Greg Studrawa has been elevated to offensive coordinator.
The 46-year-old Kragthorpe is the former head coach at Louisville (2007-09) and at Tulsa (2003-06). He replaced Gary Crowton on the LSU staff after Crowton left to take a position at Maryland.
The Tigers are expected to hold a news conference Thursday afternoon.
