One day after retiring, Conor McGregor's trainer may have hinted at his next big move

Conor McGregor might have other options outside of UFC.

Move over Brock Lesnar, Conor McGregor may be joining you in the WWE before long.

One day after retiring from the UFC following a disagreement between McGregor and UFC President Dana White, rumors are swirling that the one-time featherweight champion could jump to the WWE.

McGregor followed wrestlers Triple H, Stephanie McMahon and Shane McMahon on Twitter, and now his trainer Instagrammed a picture of legendary wrestling manager Jimmy Hart.

If McGregor does jump to pro wrestling, will he be able to top Ronda Rousey's appearance at Wrestlemania last year?
