On my drive to work this morning, the sports radio knuckleheads were blabbering on when something they said actually caught my attention (for once).  They briefly discussed an incident where JUpton approached Tulo during Rockies batting practice and flatly asked "Do we have a problem?"  They suggested that there was bad blood and bad words between the two players.

Can anyone fill me in on the nitty gritty?  Point me to articles discussing?  I LOVE this rivalry, and HATE the rox.
