The Michigan football family has just added to its roster, as head coach Jim Harbaugh announced the birth of his son, John -- "our newest Wolverine teammate" Wednesday on his Twitter account.

And while born prematurely, it looks like John is already a star player on the team, as the newest member of the Harbaugh clan is apparently already talking and firmly in his father's camp:

John -- who shares a name with Jim's brother and Baltimore Ravens coach -- is Coach Harbaugh's fourth child with his wife, Sarah, and his seventh altogether. He also has three children from a previous marriage.

Just four kids shy of a Harbaugh football team.
