Ricky Watters -- Richard Sherman Must Play ... Even If GF Goes Into Labor

Win the Super Bowl ... THEN be with you family ... that's how Richard Sherman should prioritize if his pregnant GF goes into labor right before the game -- so says ex-NFL star Ricky Watters.

The former Super Bowl champ was rocking his SB ring out in AZ last night when we asked about the real-life dilemma Sherman could be facing tomorrow.

FYI -- Sherman's GF is due very soon ... and in the case the baby decides to make his grand entrance on Super Bowl Sunday, Richard will have to make a choice.
