The Detroit Lions will be getting another member of the family as quarterback Matthew Stafford and his wife, Kelly, announce they're expecting their third child.

Kelly Stafford posted around 1 Tuesday afternoon a photo of the family of four on a beach with her clearly showing a baby bump.

She wrote that it's tough to keep it a secret and said she even got to surprise Stafford on Christmas morning:

Doing the math on the Instagram post, Kelly and Matthew should be welcoming their third child by August, the middle of Lions training camp.

The Stafford family expanded to four when they had twins last spring.
