With a planned welterweight fight between Jake Shields vs. Joe Riggs scrapped for Strikeforce’s April 11 debut on Showtime, matchmakers must now secure a fifth fight for the telecast, which is scheduled to be headlined by a 179 pound catchweight fight between Frank Shamrock and Nick Diaz.

Strikeforce officials are mulling several options for the fifth fight and Strikeforce Founder and CEO Scott Coker is quoted as telling MMAjunkie.com that a fight involving Riggs vs. Phil Baroni was a potential option.

However, FiveOuncesOfPain.com has spoken with a source speaking on the condition of anonymity who indicated that a Riggs vs. Baroni fight will not be taking place on April 11.

As of now, a fight has not been finalized for the fifth and final television slot. Riggs is still a potential candidate to compete on the card if a suitable opponent can be secured and Coker also indicated to FiveOuncesOfPain.com’s Jay Tan on Thursday that Brett Rogers is under consideration for the slot as well.
