Brock Lesnar's MMA career might be over, but it appears as though his World Wrestling Entertainment run isn't just yet.

According to WrestlingObserver.com, Lesnar is currently in Miami, site of Sunday's WrestleMania 28 event. The Web site also reported an "unconfirmed" story that Lesnar has already signed a new one-year deal with WWE.

When contacted by MMAFighting.com, UFC president Dana White said he didn't know whether the report was accurate, but added that he wouldn't have an issue with Lesnar signing with WWE, if it was true.
Several pro wrestling Web sites are reporting rumors that Lesnar will appear on tonight's WWE pay-per-view, however, none of the reports have been confirmed by WWE or Lesnar.

Lesnar retired from MMA in December after losing via first-round TKO to Alistair Overeem at UFC 140. The 34-year-old Lesnar hasn't performed for WWE since 2004.
