Forget the football hangover ... the XFL has announced it's official kickoff date -- Feb. 8 -- just 6 days after the NFL wraps up the 2019 season.
The Super Bowl goes down on Feb. 2 ... and the following weekend, the XFL will debut with a prime-time game on ABC featuring ex-Ohio State QB Cardale Jones.
Cardale -- a 4th-round pick in the 2016 NFL Draft -- is the face of the D.C. Defenders, which takes on the Seattle Dragons, coached by Jim Zorn.
The Defenders also feature WR Max McCaffrey -- brother of Carolina Panthers star running back Christian McCaffrey.
