Great Britain take on Argentina in the Davis Cup semi-final on Friday, in what will inevitably be an emotional encounter following the death of the Murray brothers’ grandfather.
Continuing the defence of the title they won last year, Great Britain take on Argentina at the Emirates Arena, Glasgow, with both Murrays set to play, despite losing their paternal grandfather, Gordon, this week.
Two-time Olympic champion Andy will kick the tie off on Friday with a mouth-watering rubber against Juan Martin Del Potro, the man he beat in a four-set classic to win Rio gold.
Captain Leon Smith has preferred 21-year-old Kyle Edmund to Dan Evans, after both men impressed at the recent US Open.
Edmund recorded wins over Richard Gasquet and John Isner before eventually being knocked out by Novak Djokovic, in the fourth round, and will face Guido Pella in Friday’s second singles match.
"It's a difficult choice because both Dan and Kyle are playing great tennis," said Smith.
"They're pretty much neck and neck in the rankings, they both have really good Davis Cup experience now."
Jamie Murray is not expected to be present on the first day as he attends his grandfather’s funeral, but is scheduled to return on Saturday to team up with his brother for what will be an emotional match against Federico Delbonis and Leonardo Mayer.
Sunday will then see the reverse singles and Edmund who, in Andy Murray’s absence, led Great Britain to victory over Serbia in the second round, will hope his enhanced Davis Cup experience and confidence will be beneficial in Glasgow.
"It gave me good confidence, gave me that belief that I can play best-of-five set matches in an intense environment and get the win,” said the Yorkshireman.
“Throughout the year you are playing on your own, in Davis Cup you're playing for the fans and I like that."
Great Britain are aiming to defend the title for the first time since 1936, and become only the sixth team to retain the trophy since the World Group was introduced in 1981.
But Del Potro, the 2009 US Open champion and double Olympic medallist, will be out to end Britain’s title defence.
"I will be fresh on Friday and I know how my level is at this moment," said the 27-year-old. "I will try to play aggressive all the time. We'll see if I can give the first point to my team."
