It has been a remarkable week for WWE and UFC fans as it was confirmed that Brock Lesnar will be returning to the Octagon for UFC 200 - despite still being a WWE Superstar.
The two rival promotions who have seen stars cross over from the octagon to the squared circle before, will now see one of the biggest names in both set to highlight two of their biggest shows of the year.
Already surrounded by controversy
Lesnar stole the headlines when he revealed that he had been granted permission to return to the UFC, but he has already been dragged into headlines regarding drugs.

Lesnar s widely regarded as the biggest powerhouse on the WWE roster and given the short space of time until he returns to the UFC, it was first reported that he will given an exemption from the pre- fight drug testing too.
That has proved false however as the USADA (U.S. Anti- Doping Agency) have now confirmed that they tested Lesnar on Wednesday.
They could have arguably been persuaded to do so after the comments from Lesnar's upcoming UFC opponent Mark Hunt.
Hunt did an interview where he claimed that Lesnar was "juiced to the gills."
It was then announced that Lesnar has been tested and that the results will be available on an open database some time next week.
It is however worth noting that one failure in these exams will result in Lesnar being banned from the sport for two years.
While this could all be above board, it is now going to be interesting to see what the results will be and how this could hype the fight further if Lesnar is cleared.
Another return soon
While Lesnar is now preparing for his return to UFC, he will be set for a return to the WWE following his fight against Hunt.
Lesnar is set to be in action at this year's Summer Slam although there is currently no rumours on who he could face.
One big name that could be set to take on Lesnar at Summer Slam could be Bray Wyatt in the resumption of a feud that we saw start at the Royal Rumble.
Summer Slam this year could be an incredible event with the WWE roster looking rejuvenated with previously injured talent.
