Kirk Cousins will soon be spending his contract money on diapers.

Cousins and his wife announced that they're expecting a baby this September. Julie Cousins posted about the news on Instagram Saturday with a picture of their dog, Bentley, holding up a sign reading, "Mom & Dad are getting me a human."

The quarterback responded to a congratulatory tweet from the Washington Redskins with, "Thanks! We're thrilled!"

The Redskins placed the exclusive franchise tag on Cousins last week. If plays next season on it, he'll make about $24 million.

Cousins, 28, made just under $20 million on the franchise tag last season. He broke his own franchise record for passing yards with 4,917 and threw for 25 touchdowns and 12 interceptions.
