Doesn't matter if the game was stopped for 2 hours and resumed, or 2 days and resumed. It's a continuation of the game, and if someone shows up ready to play, then they're allowed into the game under the rules you agreed upon at the start of the season. Doesn't matter if he's their ringer or worst player.
I call a lot of senior ball, and I swear I hear more whining about these sorts of issues in senior ball than I do anywhere else. Stop worrying about things that don't really matter. You're alive, you've got the sun on your face, a glove in your hand, and you're still playing ball.
What more can you ask for?
