Banners welcoming Heisman Trophy-winning quarterback Johnny Manziel to Under Armour's Locust Point headquarters have sparked rumors of a potential endorsement deal.

The Sun reported Monday on the appearance of the signs, including a banner that said, "Welcome To Our House, Johnny."


But the sports apparel and footwear brand has no news to share regarding the high profile Texas A&M football player known as "Johnny Football," an Under Armour executive said Wednesday.

"We have athletes and schools come and visit us, to see the campus or talk about potential deals, but we have nothing to announce on Johnny Manziel," said Matt Mirchin, Under Armour executive vice president of global marketing. "He's a great athlete and a great football player, and we think he will have a great career. It was nice to see him on campus."

Whatever comes of the visit, Under Armour has had plenty of news to confirm in the past week or so.

The visit by Manziel preceded a trip by Under Armour CEO Kevin Plank to South Bend, Ind., where Plank and University of Notre Dame officials on Tuesday announced a 10-year exclusive deal for Under Armour to supply all the school's men's and women's varsity teams with footwear, apparel, equipment and game-day uniforms. It is the largest deal of its kind in college football, according to Notre Dame.

And that announcement came just five days after Under Armour announced the brand will outfit all Naval Academy varsity teams starting in the 2014-2015 season.

If Manziel, who said he is entering the 2014 NFL draft, does end up signing an endorsement deal with the sports brand, he will join NFL quarterbacks Tom Brady and Cam Newton on the Under Armour team.

Mirchin said only that Manziel visited during the past week.

"We just wanted to meet and greet and get to know each other," Mirchin said.
