Leuluai, 28, missed the 42-24 win over Samoa with a groin injury, but will start in Avignon, and Kearney also promised to give game time to those who missed out at Warrington on Sunday.
Kearney said after the Samoa game: “Tommy ran today (Sunday) and has been feeling really good the last few days. There was a chance he could have played against Samoa. He’ll be a definite starter on Friday next week.
“We’ve got the luxury of having the personnel we do in the halves; Shaun (Johnson), Kieran (Foran) and Thomas who plays in the halves and at dummy half, so we’ll see what fits the game on Friday and make a decision from there.”
When asked if he planned to rotate his squad and give everybody in it gametime, he added: “That was always the idea. The depth of the talent sitting on the bench, the likes of Jason Nightingale, Greg Eastwood and Ben Matulino, guys of that nature.
“They’ll definitely be playing next week. After tonight’s performance, hopefully it will light a fire amongst a few of them so that they put their best foot forward next week.”
Frank-Paul Nu’uausala also took a knock that left him with suspected concussion, but he was fine after the game, according to Kearney.
