John Wall in trouble with Washington Wizards fans after sporting Dallas Cowboys jersey

LANDOVER, Md., Sept. 19 (UPI) -- Despite growing up in North Carolina and playing the first six years of his NBA career for the Washington Wizards, John Wall wore a Dallas Cowboys jersey Sunday in Landover.

Washington Redskins fans weren't too happy after seeing the All-Star point guard wearing a throwback Emmitt Smith jersey.

"John Wall was wearing a Emmitt Smith jersey," J.P. Flaim said on CSN Mid-Atlantic. "This is a guy from the Wizards, that calls out the D.C. fans for rooting for other teams and he shows up at FedEx with a Cowboys jersey?"

Wall also threw up "the X" hand signal to Cowboys wide receiver Dez Bryant before the two had a sideline chat, as noted by Jon Machota. Wall has previously worn Washington jerseys, but the move is peculiar for the guard who is signed through 2018. The 26-year-old had two knee surgeries this offseason.

"That just goes to show you, there is definitely talking for no reason," former Redskins wide receiver Santana Moss said, regarding Wall's talk about fan loyalty.

Wall supports the Cowboys mostly because of his mom's love for the franchise.

"I'm a mama's boy and that's my mama's team," Wall told the Dallas Morning News.

Fellow Wizards guard Bradley Beal also showed love to the Cowboys Sunday by posting a photo of running back Ezekiel Elliott to Instagram.

The three-time All-Star has averaged 18 points, 9 assists, and 4.5 rebounds per game during his NBA career.
