Cummins revealed Gale's mother had passed away after following a lengthy illness, with the 25-year-old not included in the Bradford 17 that suffered a 26-12 defeat against Warrington at Provident Stadium.
"We've had to deal with some stuff over this year but at the end of the day you can't worry about the result when his family has lost his mum," said Cummins. "We're going to pay tribute to Luke and on the way he's handled it for the past few months."
He added: "It's been a real difficult time for him and he's trying to keep everything normal. Our thoughts are with Luke and his family."
Bradford fought gamely against a far superior Warrington side and even won the second half 12-6 after trailing 20-0 at the interval.
Chev Walker and James Donaldson grabbed consolation tries for Bradford and their never-say-die attitude pleased Cummins, despite watching his side slide to their fifth consecutive defeat.
"We still worked hard in the first half, they had a great start and dominated all those repeat sets which makes it difficult," added Cummins. "It's probably defined our year so far; character and spirit. The personnel we didn't have out there, it was always going to be difficult, but I'm glad with the way we played in the second half.
"We opened them up. We showed some character and showed a little bit of flair. I'm glad they kept playing until the end."
Warrington coach Tony Smith admitted his side were far from their best as they moved to within two points of Super League leaders Wigan.
"We lacked intensity in the match but sometimes you can't be at your very, very best all the time," said Smith. "I thought our opponents hung in there, tried really hard and were rewarded with a couple of late tries. Well done to them, they really showed their spirit."
