The French midfielder recently went back to parent club Manchester City at the end of his initial loan spell, but has returned to Hillsborough until May.
But manager Dave Jones, who has several selection dilemmas, could opt to start with Helan on the substitutes' bench following the display last week of Danny Pugh, who recently arrived on loan from Leeds.
Another recent loan signing, Swansea striker Leroy Lita, could also force his way into Jones' starting line-up. He scored the winner after stepping off the bench on his Owls debut at Charlton.
Jones, who has no new injury or suspension worries, must decide whether to stick with Jermaine Johnson and Michail Antonio up front or hand Lita his full debut.
Wednesday, four points clear of the bottom three, are chasing their first home win in four matches.
