British number one Andy Murray has confirmed that he will work alongside new coach Jonas Bjorkman until at least the end of the summer.
The initial arrangement between the pair had been a five-week trial period.
However, with Murray's main coach Amelie Mauresmo due to give birth to her first child in August, the 27-year-old Scot has revealed that Bjorkman will now be in his box for both Wimbledon and the US Open.
"After Wimbledon, providing everything is good, I'm going to spend the whole of the hard-court stretch through to the end of the US Open with Jonas," Murray said in a statement.
"Then I'll see what happens with Amelie because I don't think she knows what her priorities are going to be and how she wants to deal with things so we'll just see for a few months."
The duo will link up for the first time at BMW Open in Munich this week.
