Castleford Tigers will have on-loan forwards Ben Davies and Rob Parker available for Sunday's Challenge Cup quarter-final.
Both players have been given the green light by their parent clubs to face Huddersfield Giants.
Wigan have cleared Davies, 21, to play, while Salford have allowed 30-year-old Parker to compete.
Castleford chief executive Richard Wright said: "Having both available to play is a boost for our chances."
"I'd like to thank both Salford and Wigan for allowing us to consider the players for selection," Wright added.
"I can't remember a bigger game taking place at the PROBIZ Coliseum in many years."
Davies scored on his debut for Castleford on Saturday against Crusaders while Parker has weighed in with two tries in three matches during his loan spell.
It is further good news for the Tigers after Rangi Chase had his ban for punching reduced to one game, leaving him available for the Giants clash.
