Maloney, along with everyone at Wigan, has every sympathy for the Newcastle player, and wishes him a speedy recovery.
But he also told the Wigan Observer: "Callum showed a lot of character to even make the starting XI, because I know he was struggling in the lead-up.
"His performance in the first half was absolutely brilliant, and it gave us a massive lift and got us off to a good start.
"The tackle will take the headlines, and that's a shame.
"You don't want to see any player being carried off the field with a serious injury, but I know Callum wouldn't have meant to hurt the player."
