"Right now the biggest focus is the Cowboys," Beckham Jr. said in the Instagram video. "There's always going to be things that go on in my life - incidences, distractions, whatever you want to call them. Right now my focus is way bigger -- it's on Dallas."
Beckham Jr. and the Giants are heading to Arlington, Texas, on Sunday to face the Dallas Cowboys in their first game of the regular season.
The controversy between the two celebs stems from Dunham's discussion of this year's Met Gala with Schumer for the Lenny Letter, an online newsletter Dunham runs with Girls showrunner Jenni Konner. The majority of Dunham's comments about the event concerned Beckham Jr.'s seeming disinterest in her.
"It was so amazing because it was like he looked at me and he determined I was not the shape of a woman by his standards. He was like, 'That's a marshmallow. That's a child. That's a dog,'" Dunham recalled. "It wasn't mean -- he just seemed confused."
Dunham, 30, has since apologized for what she called "totally narcissistic assumptions about what [Beckham] was thinking."
.@OBJ_3 is talented, stylish, seems super awesome and wasn't into chatting with me at a fancy party.
"[Beckham Jr.] is talented, stylish, seems super awesome and wasn't into chatting with me at a fancy party. My story about him was clearly (to me) about my own insecurities as an average-bodied woman at a table of supermodels & athletes," she wrote through several tweets. "It's not an assumption about who he is or an expectation of sexual attention. It's my sense of humor, which has kept me alive for 30 years. Glad the outrage machine roars on though, right @amyschumer?"
