Jose Aldo takes Twitter shot at Conor McGregor after missing media obligations for UFC 200

The bad blood between current Ultimate Fighting Championship (UFC) Featherweight champion Conor McGregor (19-3) and former divisional kingpin Jose Aldo (25-2) is real. At times, it's thick enough to clog a main artery.

Remember, it took the Irish knockout artist a mere 13 seconds to finish the Brazilian legend at UFC 194 to claim the 145-pound title.

So after McGregor was recently pulled from his UFC 200 rematch with Nate Diaz, who is still on pace to fight on the July 9 card with no opponent in mind, following missed media obligations earlier this week, it came as no surprise that Aldo wasted little time in taking his shot at "Notorious" via social media:

Aldo is currently slated to fight Frankie Edgar (20-4-1) in their own rematch (Aldo won the first meeting via unanimous decision at UFC 156) at UFC 200 for the interim Featherweight title, so maybe the 29-year-old should focus more on that matchup than bashing the hottest ticket in the game.
