Trotz said Saturday that Winnik's ear "wasn't as bad" as he said on Thursday and "I didn't really see it before."
"Any time you get hit in the ear with the puck, it's going to get chewed up," Trotz said.
The Capitals trainer used glue to close the cut and Winnik returned to finish the game. He said he had a "stinging, tingling, numbness" in his ear for "five, 10 minutes."
"It was hard to eat after the game as well or even open my mouth," Winnik said. "When [Marcus Johansson] scored, I got up and gave a big 'Yeah!' And I was like, 'Oh.'"
But Winnik said he did not have a headache afterward.
"That was good, too," he said. "That was probably the biggest thing I dodged, is any type of concussion."
Despite his scare, Winnik said he has no intention of wearing a visor now or using the protective earpieces some players wear on their helmets. Winnik is the lone Capitals player to not wear a visor.
"My face has been banged up a lot over the years and I still haven't worn a visor," he said. "I probably broke my nose 15 times or something. I just can't wear it. And the ear pieces, I think you're just used to wearing [a helmet] for so long without it. When you take them out, you're like, 'Why in the [heck] was I wearing an ear piece in the first place?' But, I guess this is an indication of why guys do."
To begin the 2013-14 season, the NHL made visors mandatory for players who did not have at least 25 games of experience in the League. Winnik, 31, has played in 649 NHL regular season games.
Trotz said the Capitals "encourage" their players to wear visors, but "they're on their own on that."
Winnik said his wife, Taylor, is "fine" with him playing without one.
"We both know whenever my playing days are done it's going to take some facial surgery somewhere along the way," he said.
