He will miss both legs of the Europa League last-32 tie against Besiktas and both Round of 16 matches if Liverpool advance.
The 20-year-old Serbian midfielder was handed an extra match ban because he was sent off playing for Benfica against Juventus in last season's Europa League semi-final when he was red-carded after rowing with the referee following his late substitution.
Markovic's dismissal against Basel was hotly disputed by Liverpool because, as he ran with the ball he appeared to push his hand into the face of the chasing Behrang Safari but he never looked behind him to check where the opponent was.
