Rumors have been swirling about Brock Lesnar potentially returning to the UFC, and his appearance Monday on "WWE Raw" only added to the speculation.
Speaking on his behalf, Lesnar's advocate, Paul Heyman, told "Raw" general manager Kurt Angle that if the Beast Incarnate fails to retain his Universal Championship at SummerSlam, they'll both leave WWE.
Lesnar reportedly hasn't re-enrolled in the USADA's testing pool, but did respond to a challenge from new UFC light heavyweight champion Jon Jones on Saturday, telling him to "be careful what you wish for, young man."
