Lisa McCune drama shunted into late night Fridays Lisa McCune as Sam Rohan and Nichol as Toby in the the ill-fated Channel 10 show 'Reef Doctors'. CHANNEL 10 has confirmed that it is set to drop Reef Doctors from its prime Sunday night slot after one episode. Ten's move comes after the Lisa McCune drama posted one of the worst ratings debuts for an Aussie drama on record on Sunday night. The much-delayed adventure managed a pitiful 357,000 viewers nationally - crushed by rivals The Block Sky High (1.3 million viewers) and Sunday Night (1.133 million). The poor Reef Doctors figure had a flow-on effect with MasterChef Australia slumping to 648,000 viewers Sunday night. Ten is set to announce that Reef Doctors will now air in a late night graveyard timeslot. "Reef Doctors will now air Friday nights at 9.30pm from Friday, June 21," Ten spokesperson Catherine Donovan says. Ten will replace Reef Doctors on Sundays at 6.30pm with double episodes of US sitcom Modern Family. The move is a blow for McCune who co-produced as well as starred in Reef Doctors. The show was squarely aimed at families and they will be in short supply in the new late night timeslot. McCune, who is best known for hits Blue Heelers and Sea Patrol, plays single mum Dr Sam Stewart who heads up the remote Hope Island clinic.
