The 24-year-old former London Broncos half-back, who was in the form of his life for the Bulls last season, has yet to play this year after damaging his ankle playing for the Knights in the autumn but is now back in full training and is poised to make his comeback against his old club in Saturday's clash at Adams Park.
With Jarrod Sammut combining effectively with makeshift stand-off Danny Addy during Bradford's impressive start to the season under Cummins, Gale is not guaranteed a spot and is likely to have to settle for a place on the bench. Cummins said: "He's in full training now but I'm not just going to pick Galey because I want him to play."
He added: "It's got to fit in with the team. He's got to work his way back in. He was really good last year, especially at the back end, and when he takes on the line he makes a great decision, which is probably what we can do with.
"On the whole, Danny and Jarrod have done very well and now hopefully we've got three in there so something's got to give."
Cummins, promoted to head coach following the departure of Mick Potter at the end of last season, was forced to operate with one of the smallest squads in Super League as a result of the club's financial difficulties in 2012.
His resources were depleted further with the loss of Gale and centre Adrian Purtell for the start of the season but all three are now fit and Cummins is close to being spoilt for choice.
"We've got some headaches around the corner but that's what I've looked forward to from the first week of the season," he said. "We're now getting people back and there are going to be some disappointments.
"It's important people don't sulk and instead do their best for the team. Whether they are involved in the game or not, they can still contribute and make a difference. It's about doing what is best for the team."
Bradford are still waiting to discover the extent of the ankle injury sustained by goalkicking winger Jamie Foster during yesterday's 34-22 win over Salford and Cummins will also check on the fitness of John Bateman, Matty Blythe, Matt Diskin and Chev Walker before finalising his squad for the trip to London.
