UFC has responded to the Strikeforce show on CBS by announcing a competing show of their own.
Dana White confirmed today that UFC is running a show on April 17th, head-to-head with the announced Strikeforce show on CBS. There are no fights confirmed, although Matt Serra vs. Mike Swick is being finalized for the event. A fight between Wanderlei Silva vs. Yoshihiro Akiyama is not scheduled for the event.
The proposed UFC event would air on Spike TV. Strikeforce could move the date of the CBS show by a week, moving it head to head with the WEC PPV on April 24 from Sacramento.
