Wimbledon champion Andy Murray says it is "unlikely" he will play in Great Britain's Davis Cup quarter-final against Serbia in Belgrade this week.
The 29-year-old beat Milos Raonic in straight sets on Sunday to win his second Wimbledon title.
A final decision on his Davis Cup participation will be made after talks with captain Leon Smith.
World number one Novak Djokovic, beaten in the third round at Wimbledon, has already withdrawn from the Serbia team.
Murray played a pivotal role as Britain won the Davis Cup for the first time since 1936 by beating Belgium in Ghent last November.
