Hull KR half-back Mikey Lewis will miss up to two months of action through injury.
Lewis, 20, will be sidelined between six to eight weeks following an ankle injury sustained against Castleford in the Challenge Cup.
The Robins secured their spot in the semi-finals of the cup competition following a 34-10 victory at Craven Park.
However, Lewis left the field with an ankle injury and was pictured in crutches following full-time.
He will undergo surgery which will see him miss almost two months of game time.
