Former Auburn wide receiver Sammie Coates has landed an endorsement deal with Under Armour, the company's official Twitter account revealed Monday night.

Coates joins an Under Armour stable that includes former Auburn quarterback Cam Newton, former Alabama stars Eddie Lacy and Julio Jones and San Francisco 49ers teammates Eric Reid and Vance McDonald.

Coates, who is projected as a first or second-round pick, confirmed the news by tweeting back at the company.

"Happy to be with the family," Coates said.

By choosing Under Armour, Coates is sticking with what he wore in college. Auburn has an official apparel agreement with Under Armour.

Coates is coming off of an impressive Senior Bowl week in Mobile, although he was forced from the game early due to a groin injury on Saturday.

But his stock rose during the week, both as a deep threat and as a red-zone target capable of going up and making tough catches over the top.

Now, Coates has to try to recover from that groin injury and build on his Senior Bowl week with an impressive showing at the NFL Combine in three weeks. A freakish athlete at 6-foot-2, 213 pounds, Coates is expected to turn in one of the best workouts among a deep wide receiver class.
