Swansea overcame the first minute sending-off of a player to secure a goalless draw in the first leg of their English football Championship playoff semi-final away to Nottingham Forest.
The Swans, who finished the regular season in third place, four points adrift of the two automatic promotion spots to the English Premier League, were a man down as early as 52 seconds.
The teams meet for the second and final leg of their semi-final at Swansea's Liberty Stadium ground next Tuesday.
Swansea's Welsh rivals Cardiff meet Reading in their first leg play-off match today.
The winner of the play-off final, labelled the richest game in football as the winners go into the lucrative Premier League, will join QPR and Norwich in the top flight next season.
