The Jacksonville Jaguars have named Luke Butkus interim offensive line coach, tabbing him to fill in for cancer-stricken assistant George Yarno.
Yarno left the team last month and returned home to be with his family in Spokane, Washington, while he undergoes treatment.
Coach Gus Bradley says the 56-year-old Yarno will be away from the team for "some months."
Bradley says Yarno is "encouraged by the progress" and adds "We're all rooting for him and we'll welcome him back with open arms when he comes back."
Butkus, entering his seventh NFL season, is a nephew of Hall of Fame linebacker Dick Butkus.
The Jaguars also hired Matt Applebaum as an offensive assistant. Applebaum will work primarily with the O-line.
