There have been rumors in the MMA world of Brock Lesnar returning to UFC and that Lesnar will be attending Saturday’s UFC 168 event in Las Vegas.

During Thursday’s post-press conference media event, UFC president Dana White was asked if UFC would take the opportunity to talk business with Lesnar. He replied:

“I honestly don’t know. Honestly, I don’t know.”

Sources close to Lesnar told MMAFighting.com’s Ariel Helwani that they didn’t think Lesnar was very serious about returning.
