David Perron returned to the St. Louis Blues' lineup Saturday with tears of joy streaming down his face after missing nearly two months with a concussion.
He explained his raw emotion to NHL.com's Lou Korac on Wednesday.
"Because it's harder and harder every time," Perron said, according to Korac's In The Slot blog. "It's so hard on the mental side of it to go through. Basically, you have some situations that heal up quicker, and some that linger and there's no reason why, and that's why it gets harder on you, it gets harder on your family, you start to wonder about other things and you get in your head a lot.
"It's just good to be back. I think when you play, you think less and everything kind of settles."
Perron suffered his first concussion during the 2010-11 season after taking a blindside hit from Joe Thornton. He ended up missing 97 games.
