2:18 PM PT -- Gruden and Carr tried their best ... but they weren't able to get their captain back. The NFL just announced Burfict's suspension has been upheld.
See ya next year, Vontaze.
Oakland Raiders linebacker Vontaze Burfict had support from his coach and star QB during his appeal of a season-ending suspension … with Jon Gruden and Derek Carr vouching for the controversial player.
Burfict was banned from the league for the remainder of the 2019-2020 season after his violent helmet-to-helmet hit on Colts tight end Jack Doyle during their Week 4 match-up.
The 29-year-old spoke with league officials for more than an hour on Wednesday ... in an attempt to get back sooner than next season.
