Malik Nabers isn't gonna let a division rivalry stop him from cheering for his friend and former teammate ... 'cause the Giants star was losing it in the stands after Jayden Daniels led his Commanders to a huge playoff victory!!
Nabers and fellow ex-LSU receiver/Jaguars rookie Brian Thomas Jr. hit up Raymond James Stadium in Tampa for the Commanders' Wild Card matchup with the Buccaneers ... and even though N.Y. and Washington go together like oil and water, the two set aside their employers for a night to cheer on their buddy.
