Former UFC Heavyweight Champion Brock Lesnar was sitting cageside at UFC 146 last night, and was shown on camera watching UFC Heavyweight Champion Junior dos Santos defeat Frank Mir.

UFC President Dana White hinted at Lesnar returning to the organization at the evening's post-fight press conference. When asked if Lesnar's appearance meant anything, White smiled and replied, "maybe," before flat-out admitting the Lesnar may be headed back to the company. White went on to say that he hadn't spoken to Lesnar, but he would let everyone know if anything happens.

PWInsider reports that Paul Heyman was also in Las Vegas, the site of UFC 146, this week.

Lesnar re-signed with WWE in April and is contracted to appear for the company through Wrestlemania 29.
