Andy Murray's father-in-law collapses at Australian Open: Nigel Sears is carried out of arena on a stretcher just weeks before his daughter Kim is due to give birth

Andy Murray's father-in-law Nigel Sears collapsed at the Australian Open - just weeks before his daughter Kim is due to give birth. 

Sussex-based Sears, 58, fell ill during the third round match between Ana Ivanovic - who he coaches - and Madison Keys today. 

He was treated by paramedics in the stands and then stretchered away with his shirt off and attached to an oxygen tank.

He is understood to have been conscious and alert as he was taken to hospital.

Murray was unaware of what had happened as he was playing on a neighbouring court. He was informed after his match by his mother, Judy, and went straight to the hospital.
