Sean McVay had an extra special Father's Day ... 'cause the L.A. Rams head coach and his wife, Veronika Khomyn, just announced he's going to be a daddy later this year -- and it's a boy!!
The couple shared the big news on Sunday ... showing off Veronika's growing baby bump and pictures of her sonogram.
The Super Bowl-winning coach will have his hands full this season ... as the new arrival is slated to come during the start of the 2023-24 campaign.
