Andy Murray's elbow injury is set to keep him out of the Davis Cup quarter-final tie with France next week, according to brother Jamie.
The world number one was forced to withdraw from the Miami Open after suffering the injury practising for the event and returned to Britain last week where a scan revealed the damage.
Jamie revealed Andy has torn part of his right elbow and his participation in the clash in Rouen, which begins a week on Friday, now appears unlikely.
Jamie told The Times: "It's some sort of tear in his elbow, so he needs to rest.
"He said he can do everything except serve and he told me that rest was all he had to do. I am not planning that he is going be there (against France) but, if he is, then obviously that is great for the team and we'll see what happens.
"But the most important thing for him is just to get healthy because he has had a few issues now. He has had shingles, he has had his elbow, he was sick here as well for two or three days after he pulled out of the tournament.
"I think he just needs to get a bit settled and get a good crack at it over the next three months because there are a lot of big tournaments to play."
