PHOENIX -- Richard Sherman isn't just preparing for the New England Patriots this week.

He's getting ready for the birth of his son.

The Seattle cornerback is on baby watch this week. His girlfriend, Ashley Moss, is expected to give birth to their son in the next week. Sherman said Wednesday a recent visit to the doctor gave him faith his son will not arrive in the next few days.

But just in case, Sherman said Moss is in Arizona with Super Bowl XLIX around the corner. If she goes into labor before Sunday, Sherman said the plan is to have her give birth at a local hospital.

But if his son decides it's time to enter the world on Sunday, Sherman may be faced with a career-defining decision.

"We'll cross that bridge when we get there," Sherman said. "We're not thinking about the possibility."

Sherman said he and Moss have picked a name for their son, but he wouldn't divulge it.

"I'm going to pass on telling you," he said with a smile. "We're keeping it a secret from everybody."

During Tuesday's Super Bowl media day, Sherman said knowing his son is on the way will give him an extra degree of motivation Sunday.

"It's someone that actually depends on you for everyday living," Sherman said. "Everything they do is dependent on you and how you provide and how successful you are.

"As a parent, you want to set a great example for them, so I guess, to a degree, a lot of things are riding on it."
