Hamilton Accies have work to do to avoid relegation to League One after Wasps boss Brian Rice stung his old side in the first leg of the Championship play-off semi-finals.
Luke Donnelly climbed off the bench for stricken team-mate Adam King to give Alloa the advantage in a tense tie at the Indodrill.
King collapsed off the ball midway through the first half and the game was halted for five minutes as he received medical treatment on the pitch.
