In a multiplayer game one of my opponents has a felidar sovereign and is at 39 life and I am at 2 life. He attacks me with a 2/2 lifelink creature, but before damage is dealt I concede. Does the lifelink still gain my opponent enough life to win with felidar sovereign at the beginning of his upkeep, thereby letting my other opponent lose the game or do I only lose and do my opponents still need to continue the game to determine who wins?
