Cronulla have secured their first major long-term naming rights sponsor in almost four years, with Southern Radiology signing on with the NRL club until the end of 2017.

Sharks skipper Paul Gallen is also a confirmed starter for Sunday afternoon’s clash against the Roosters.

The announcement is a major step in Cronulla’s rebuild and comes after years of off-field dramas, including the infamous supplements scandal of 2011 that almost brought the club to its knees.
