Beasley was one of four starters from last Saturday's 4-2 loss to Hearts -- Rangers' first of the Scottish Premier League season -- to find himself on the bench at the start of the Group E match against Stuttgart.
He came on in the 67th minute for Charlie Adam shortly after Adam's well-taken equalizer. Rangers won the game in the 71st minute on French Guyanan Jean-Claude Darcheville's penalty kick after right back Alan Hutton was taken down in the box.
Beasley previously played for PSV Eindhoven in the 2004-05 and 2005-06 Champions League campaigns.
