Andy Murray faces a drop to his lowest world tennis ranking for six years after his surprise quarter-final exit at Wimbledon.
The 2013 champion, beaten in straight sets by Grigor Dimitrov, is likely to be 10th when the updated ATP rankings are announced on Monday.
Murray, 27, who was fifth going into Wimbledon, will have his worst listing since June 2008, when he was 11th.
The Briton missed three months at the end of last year after back surgery.
He has not beaten a top-10 player since last year's Wimbledon final.
However he had not dropped a set in four matches at Wimbledon 2014 before going down 6-4 7-6 (7-4) 6-2 in two hours to 23-year-old Dimitrov.
The Bulgarian, currently at 13, is likely to overtake Scot Murray - who was at a career-high second after his Wimbledon title last year - in the rankings whatever the result of his semi-final against 2011 champion Novak Djokovic on Friday.

Newspapers on Thursday suggested Murray had been distracted during the game, and had sworn in the direction of the players' box while reportedly shouting: "Five minutes before the match."
It is not clear what his comments were referring to, although Murray's match did start earlier than normal.
His mother Judy was in the players' box from the second set, alongside his girlfriend Kim Sears and coaching team, headed by Amelie Mauresmo, who was there from the start.
Asked if he had suffered any distractions before the match, Judy told BBC Radio 5 live: "No, not that I'm aware of.
"I missed the whole of the first set because I was watching (his brother) Jamie play mixed doubles on court 18."
She added: "Andy just didn't manage to find his best form and struggled for rhythm throughout the match.
"When you are on such a big stage as this in front of your home crowd, it's so difficult to take that you haven't found your best form."
She said he was due to meet up with Mauresmo on Thursday morning.
"I'm sure he'll be back. As they say, form is temporary, class is permanent," added Judy.
