OXNARD, Calif. – What was first hinted at in the spring has become official: Tony Romo has an endorsement deal with Under Armour .

The first hint came in the offseason when the Dallas Cowboys quarterback put a pair of Under Armour cleats in a prominent position in his locker as he spoke to the media. At training camp, Romo has worn the cleats and sported an Under Armour hat when featured on an ESPN interview with Jason Witten earlier this week.

He is the third high-profile quarterback to join the apparel company, with Tom Brady and Cam Newton.

Romo had been a free agent of sorts since his deal with Starter expired in 2013. He had worn Nike cleats but painted over the logo in recent years.

The addition of Romo to Under Armour allows for a Dallas-centric marketing opportunity with golfer Jordan Spieth.

Spieth recently signed a 10-year contract with Under Armour after winning The Masters and U.S. Open and is the second-ranked golfer in the world.

He is also good friends with Romo and has played many rounds of golf with him. They were even paired in an amateur tournament in South Carolina a few years ago.
