Andy Murray will close the opening day of Great Britain's Davis Cup contest against Luxembourg against the unranked Laurent Bram.
Murray takes on 27-year-old tennis coach Bram tomorrow at Braehead Arena in Glasgow after James Ward opens against Gilles Muller at 4pm.
Bram, who has lost nine of his previous 11 Davis Cup singles matches, stopped playing professionally four years ago.
Murray will also face Bram on Saturday as he and brother Jamie take part in their first Davis Cup doubles match as a pairing, with 18-year-old Mike Vermeer completing the quartet.
World number four Murray will then open against Muller, who is ranked 81 in the world, on Sunday afternoon before Ward and Bram complete the Europe/Africa Group II encounter.
The Wimbledon semi-finalist admitted he already felt re-energised by his involvement in the Davis Cup tie, his first under captain Leon Smith, in front of an enthusiastic Scottish crowd, with all the tickets already sold for the first day's play.
"It should be good," the British number one said. "I've had a great last few days, practised well.
"We went to a tennis club yesterday in Paisley and got really good support, everyone has been really upbeat and positive.
"That's been great, something you need this time of year. We are halfway through now so you need something to give you motivation and that has helped."
There was one change announced to the British squad with Daniel Evans replacing doubles expert Colin Fleming as the back-up player.
Smith said: "He (Fleming) had a slight niggle in his foot and that's the reason we made a switch. There is no need to gamble.
"Clearly Dan is the fourth player here and isn't listed to play but we wanted someone fully fit, if needed, to step in for the singles."
Britain will face Belarus or Hungary in a promotion play-off in September if they defeat their visitors this weekend.
