Slice weighing options

Kimbo Slice is now deciding whether to remain in Mixed Martial Arts or head to the boxing ring after he was released from his contract.

According to an SEC filing obtained by Sherdog.com, Slice (whose real name is Kevin Ferguson) was set free on May 13. His manager, Mike Imber, told the Web site that he could not reach a deal with Strikeforce, who obtained an option to purchase his contract from Pro Elite in February.

Imber told Sherdog.com that Strikeforce wanted Slice to fight for less than the $500,000 he earned in a loss to Seth Petruzelli in October.

"They wanted us to fight for less," Imber said, according to Sherdog.com. "I wouldn't say dramatically [less], but there were just a lot of moving parts in the contract. Once you start moving one, they all kind of got moved around. It just didn't work out, I guess."

While multiple reports have Slice ready to make his boxing debut, Imber said nothing is finalized.

"I can't give you any updates right now, but when I do you're going to be very impressed and shocked," Imber said, according to the Web site. "I can tell you his MMA career is far from over. We have a bunch of other options -- Japan and others. Now that we're actually free to explore them, we're doing it."

Slice was the second MMA fighter to appear on the cover of ESPN The Magazine (Chuck Liddell was the first).
