World number four Andy Murray is set to miss Britain's Davis Cup match against Belgium in Glasgow next month.
Speaking about the Davis Cup in Indian Wells, Murray hinted he was unlikely to play, particularly if he performed well in this week's Masters tournament in Miami, where he is through to the fourth round.
Victory at Braehead Arena would send Leon Smith's British team through to a World Group play-off in September, but they will be big underdogs for the Europe/Africa Zone second round match.
Belgium's singles players Olivier Rochus and Steve Darcis are ranked 52nd and 68th respectively, well ahead of Britain's James Ward (162) and Dan Evans (291).
The only rubber the hosts will be favourites to win will be the doubles, where Colin Fleming and Ross Hutchins should prevail.
