Former Pittsburgh Steelers star James Harrison has signed with the New England Patriots.

The Patriots announced the move Tuesday, three days after Harrison's unceremonious departure from Pittsburgh.

The 39-year-old linebacker posted a photo of himself with 40-year-old quarterback Tom Brady in New England's locker room on his Instagram account, writing that he finally has a teammate "that's older than me!"

Harrison visited the Patriots after clearing waviers and becoming a free agent following his release by Pittsburgh.

To make room on their roster, the Patriots released linebacker Trevor Reilly.
