RENTON, Wash. (AP) — Just as Richard Sherman predicted, his new son was a disciplined young man.

Sherman's girlfriend, Ashley Moss, gave birth to the couple's first child Thursday morning, four days after the Super Bowl. Sherman tweeted about the birth around 4 a.m. PST.

Sherman tweeted: "My son sure does know how to make an entrance! 2/5/15... Is it a coincidence or is he just that clever?! Either way I'm ecstatic."

The pending birth and what Sherman would do if Moss — who was in Arizona with the team — went into labor around game time became one of the biggest stories of Super Bowl week.

Three days before the game, Sherman joked, "I think he's going to be a disciplined young man and stay in there until after the game."
