Andy Murray is one of five players named by Great Britain for this month's Davis Cup tie with Serbia, although the world number two will not confirm his involvement until after Wimbledon.
The Scot's brother Jamie, Kyle Edmund, Dan Evans and Dom Inglot are in the team for the round two tie in Belgrade.
Murray, 29, is into the last eight at Wimbledon after beating Nick Kyrgios.
"We know what strength the Serbian team have and understand the scale of the challenge," said captain Leon Smith.
"In making himself available for the tie, Andy has once again shown incredible commitment to his country and his proven Davis Cup record is second to none.
