It has been scheduled as TBA - to be arranged - and will not start before 5pm local time on Saturday.
"I don't know what to say right now".
"Just playing like that in those conditions, it was really tough for both of us". Isner was 8-3 lifetime versus Anderson coming into the match.
Ultimately, it was Anderson who prevailed, taking the match 7-6, 6-7, 6-7, 6-4, 26-24.
Although the All England Club has a retractable roof with lights, a curfew of 11 p.m.is implemented in order not to disturb its residential neighbors in southwest London.
He stands at 0-5 with Nadal and 1-5 against Djokovic.
That service hold - helped by a 129 miles per hour (207.6km/h) second serve - took the American to 100 service games unbroken at this Wimbledon.
Isner, who said Wimbledon had become "a house of horrors" for him since his 2010 match, had been trying to become the first American to reach the finals since Andy Roddick in 2009. The fifth set lasted 175 minutes. "I'm not going to hang my hat on that, for sure", he said. "My left heel is killing me". I apologize if I'm not fully excited right now. "At the end, you don't even feel that great out there".
Today sees the men's singles semi-finals take place at Wimbledon, and looking forward to two excellent match-ups, is our tennis columnist, Dan Weston.
There are no tiebreakers in the fifth set of matches at Wimbledon.
He added: "It's a bit of a sign for the Grand Slams to change this five-set format".
It is also the second-longest match ever at a tennis major. I don't think it needs to continue.
The match proceeded with Anderson serving first in the third set, then with the South African leading 4-3, Isner's serve was broken for the first time at Wimbledon after 110 consecutive service holds, for Anderson to lead 5-3.
Anderson finished the match with 49 aces and 118 winners; Isner had 53 aces and 129 winners.
Experience will play a big part here for Anderson - he has been in this position before and alas he capitulated completely to Rafael Nadal in the US Open final past year, but it is a series of matches that will have served him in good stead. Anderson's win over John Isner lasted 6 ½ hours and went to 26-24 in the fifth set. There were two crucial moments in the opening set before the tie break, when Anderson saved three break points in game three to survive an early scare and in game 10 when John repelled a set point.
That point ended up actually setting up the winning break for Anderson. The record, funnily enough, was set by Isner.
With a duration of 6 hours and 36 minutes, it is the longest semifinal in Wimbledon history.
Of course, Isner has a consistent serve as his main weapon and when combined with his forehand, is possessed of a solid one-two punch combination.
With Anderson serving for the final at 25-24, Isner handed his opponent two match points when a return sailed long. Not only is he advancing to the first Grand Slam semifinal of his career at Wimbledon, he and his wife, Highland Park native Madison McKinley, are expecting their first baby girl.
