Glasgow - Olympic final opponents Andy Murray and Juan Martin Del Potro will resume hostilities in Friday's opening Davis Cup semi-final singles match between holders Great Britain and Argentina in Glasgow.
The duo fought out an intense men's Olympic final in Rio de Janeiro last month, with Murray eventually prevailing after more than four hours to claim a second successive gold medal.
Thursday's draw paired them in the opening rubber at Glasgow's hard-court Emirates Arena, with Kyle Edmund then taking on Guido Pella.
Murray, the world number two, will team up with brother Jamie in Saturday's doubles against Federico Delbonis and Leonardo Mayer.
Andy Murray will tackle Pella in Sunday's penultimate singles match before Edmund, who reached the fourth round at the US Open, and world number 64 Del Potro bring the curtain down.
Britain beat Belgium 3-1 in last year's final on clay in Ghent to claim a first Davis Cup crown since 1936.
The British team, captained by Leon Smith, overcame Serbia in this year's quarter-finals, while Daniel Orsanic's Argentina defeated Italy.
The winners of the tie will play either Croatia or France in the final in November.
