Cut by Steelers, Harrison joins NFL champion Pats

Former Pittsburgh linebacker James Harrison has signed with the Patriots.

The Patriots announced the move Tuesday, three days after the Steelers cut Harrison, their all-time leader in sacks.

Harrison, 39, 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 waivers and becoming a free agent.

Harrison appeared in five games this season and ended his last season in Pittsburgh with one sack and three tackles.

“There was no animosity or bad feelings. It’s just the business of the NFL,” Bill Parise, Harrison’s agent, told ESPN’s Josina Anderson.

To make room on their roster, the Patriots released linebacker Trevor Reilly. Coaching news: Arizona head coach Bruce Arians says a report that he and the team have agreed to part ways after the season is untrue.

An article in Pro Football Weekly cited “multiple sources” as saying the split would come next week at the end of Arians’ fifth season.

Arians, 65, is 49-32-1 in five seasons with the Cardinals, including the postseason. They are 7-8 this season.

Cowboys owner Jerry Jones says head coach Jason Garrett will return for an eighth full season after Dallas missed the playoffs in a year marred by the six-game suspension of running back Ezekiel Elliott.
