Catching up with Bellator's latest moves: Riggs and welterweights

As we near the start of Bellator's fourth season in March, the promotion has had a busy start to 2011, making several announcements about the new season.

-- Season four will feature a welterweight tournament, with the winner earning $100,000 and a shot at Ben Askren and his championship belt. Askren has been busy coaching the Arizona State wrestling team and winning a wrestling "super match" with freestyle world silver medalist Jake Herbert.

-- Dan Hornbuckle will return to Bellator and fight in the welterweight tournament. He will be joined by Olympic judo player Rick Hawn and Brent Weedman, who has fought on three Bellator cards.

-- They also announced the signing of Strikeforce and UFC veteran Joe Riggs. The last time the middleweight fought was with King of the Cage in Canada. Before that, he beat Louis Taylor at Strikeforce: Challengers and lost to Jay Hieron, another Bellator signee.
