MMASucka.com's Callum Leslie and Shawn Smith from VICE Fightland are back with the GrappleTalk podcast, brought to you by MMASucka.com.

On the show this week:

• Conor McGregor, what's next for him, and how big a star is he really?

• Cung Le surprised no one when he failed a drug test for HGH, is this a good sign for the UFC's new drug testing programme?

• Dominick Cruz and Cat Zingano made emotional comebacks to the cage this weekend, and the guys discuss their title prospects.

All this plus Bellator, Battlegrounds MMA and a full preview of the weekend's MMA action.
