New England Patriots head coach Mike Vrabel is at it again -- the ex-NFL linebacker jumped into the middle of yet another scuffle during the team's joint practice with the Minnesota Vikings on Thursday ... and ended up at the bottom of a pile in the process!!
The chaos unfolded during the second workout between the two squads. While it's unclear what exactly led to tensions boiling over ... Vrabel -- who played for the Patriots for eight years -- quickly jumped in to try and end it.
