Maloney said a decision on his involvement would be made on the morning of the game but he was hopeful. "I had a run on it earlier in the week and it's a bit stiff now but we'll just have to see.
"As it turns out, the scans show it's only been strained, it hasn't been torn. It's probably the best-case scenario, it could be a lot worse."
If Maloney does not play, Carlos Tuimavave, his replacement against the Sharks, will get the nod, with yet more responsibility falling on Shaun Johnson's young shoulders.
"They've played a lot of football together and it would be good to see Shauny step up and take control of the side," Maloney said.
Reflecting on the Sharks' defeat which has all but ended the Warriors' playoff ambitions - they are in 13th place and must win their four remaining games to have a chance of making the top eight - Maloney said: "Everyone's got their pride and self respect. Every week we run out you don't want to have a game like that. There's only one way to turn it around and silence everyone, and that's to get a win and play some good footy."
The Warriors have lost their last seven games at Dairy Farmers Stadium, and lying in wait are a Cowboys side featuring the likes of Johnathan Thurston, Matthew Bowen and former Warrior Brent Tate.
Warriors' forward Feleti Mateo said his side was aware of the challenge and maintained the players were in good spirits, adding that coach Brian McClennan had been calm in his assessment of the Warriors' recent form.
"To his credit he's been more constructive than anything," Mateo said. "He knows what we need to work on, and that's what he focuses on. Nowadays you don't really get much out of a revving up from the coach, and he knows that. We're grown men, we know what we did wrong and it's just about fixing it."
