Ana Ivanovic's British coach Nigel Sears was due to be released from a Melbourne hospital on Sunday afternoon, having been dramatically carried from courtside at Rod Laver Arena after collapsing early in the second set of Ivanovic's loss to Madison Keys on Saturday. 
A bloodied Sears, 58, the father of Andy Murray's pregnant wife, Kim, was immediately treated with an IV and oxygen, and had several ECG and blood tests after leaving Melbourne Park in an ambulance. He had reportedly started feeling unwell about half an hour before the match.
"He had a couple of tests, he's doing well, and he'll be going home this afternoon," a hospital spokesman said.
Murray, with his mother Judy, went straight to visit his father-in-law after finishing his own four-set match against Portugal's Joao Sousa, while Wimbledon referee Andrew Jarrett, who is working at the Australian Open as an assistant referee, accompanied Sears in the ambulance.
"It was very worrying to begin with and when I saw him lying on the steps he looked so grey facially," Jarrett said. "But I was a lot happier when I left the hospital than when I arrived. He was totally conscious and talking very normally. All he wanted to know was how Ana's match was going.
"I'm not quite sure how all the blood ended up on the steps. I saw no sign of Nigel cutting his head at all but the sleeve of his tracksuit was blooded and maybe the medics pushed something into his arm." The Ivanovic-Keys match was interrupted for about an hour by the incident, with both players given the option not to continue, but choosing to resume. Sears' daughter Kim is at home in Britain and due to give birth next month.
Murray was not required by tournament organisers to stay on the court for the traditional winner's interview on Saturday night. His mother met him as he walked off and the two went to the tournament's transportation office, from which they were driven away.
Ivanovic and Keys were also allowed to skip their post-match media obligations. The tournament provided statements from each player about the matches but did not mention the scare that had transformed the evening.
