Thole has already sustained two concussions in his career -- one this season. Since returning from the disabled list June 1, Thole has worn a hockey style mask behind the plate, which offers added protection and padding.
"Those masks aren't easy to discard, so I think that'll help Josh a lot," Collins said.
Thole's play on Thursday -- Fontenot was thrown out at home on a throw from Scott Hairston -- ultimately proved to be the biggest defensive play of the game as the Mets overcame a Philadelphia lead in the bottom of the ninth to win 6-5.
"If I start being worried about something like that, you lose credibility with your teammates, and in that situation, you lose the game," Thole said about being cautious during collisions. "We would have had to push another run across the plate, because now we're down by two."
Thole said that despite his concussions, he has no intentions on changing his style of play.
"It's part of the game, I expect that any time I go back there," he said.
