Andy Murray concerned that Australian Open heat could put players in danger

British number one Andy Murray has expressed his concern for the players' safety and health due to the extreme heat in Melbourne.

A number of competitors have complained about the searing temperatures Down Under, and Murray has also spoken out after he secured a 6-1 6-1 6-3 win over Go Soeda in the first round.

"It only takes one bad thing to happen and it looks terrible for the whole sport," BBC Sport quotes Murray as saying. "If people are collapsing, that's obviously not great.

"Whether it's safe or not, I don't know but you've got to be careful these days. There have been issues in other sports, with people having heart attacks, with people collapsing. I wouldn't want anything bad to happen to anyone."

The Scotsman will play either Vincent Millot or American Wayne Odesnik in the second round.
