There’s room for one more Watt in Pittsburgh.

The Steelers are adding fullback Derek Watt, brother of Pro Bowl linebacker T.J. Watt, on a three-year, $9.75 million contract, a source told ESPN’s Jeremy Fowler. The deal makes Derek Watt one of the highest-paid fullbacks in the NFL.

Though the Steelers don’t run a fullback-heavy offense — fullback Roosevelt Nix hasn’t played more than 16% of snaps in a season — Watt will be a major piece of Pittsburgh’s special teams with the departure of captain Tyler Matakevich to the Buffalo Bills.
