Las Vegas Raiders star Darren Waller says he couldn't be happier for his teammate, Carl Nassib ... telling TMZ Sports the whole team will continue to love and support the guy no matter what.
28-year-old Nassib made the groundbreaking decision to come out as gay earlier this week ... becoming the first active NFL player to do so.
Waller says he was pumped for his teammate when he heard the news ... but hopes these sort of announcements aren't such a big deal in the future.
"My initial reaction was like, ‘oh, that’s dope,'" Waller tells us.
