Lehner was all for helping Foley and took it one step further by agreeing to meet with him after New York's 2-1 loss.
"I'm going to go meet a fantastic human being and see what life's about," Lehner said. "I'm really looking forward to it. It's going to put a smile on my face and make me forget about this one."
Foley, whose mom refers to him as "my half-hearted hockey player," was told he'd likely never participate in athletic activities, but has overcome the odds to complete a triathlon in 2017 and plays hockey on Long Island now.
"He's defying all the doctors' odds," Kiefer-Foley told MSG-Plus. "He's doing every single thing they said he never would."
