Guida to fill Shamrock's shoes

Following the announcement that Ken Shamrock allegedly tested positive for banned substances and was subsequently suspended by the California State Athletic Commission, the search was on for a new opponent to face BobbyLashley at the upcoming Roy Jones Jr. MMA/boxing hybrid fight card on March 21 in Pensacola, Fla.

The slot has now been filled as MMAWeekly.com confirmed on Friday that Jason Guida would step in and face the former WWE superstar as a part of the card just over one week away. Guida's participation was confirmed by sources close to the fight.

Jason Guida -- brother of UFC lightweight fighter Clay Guida -- will face Lashley currently riding a three-fight losing streak. The Illinois native was also a participant on the eighth season of The Ultimate Fighter, but was unable to make weight for his first scheduled matchup at 205 pounds and exited from the show.

The former Adrenaline and EliteXC fighter will now get ready for a major challenge in rising star Lashley, who will square off in his second ever professional MMA bout.

Lashley made a splash on the scene when he left his career as a professional wrestler with WWE behind to pursue a dream and fight in the world of MMA. Soon after, the hulking 6-foot-3 monster signed on to train with the famed American Top Team, and now looks to stay undefeated when he faces Jason Guida.

The show on March 21 will feature Jones Jr. in a boxing match, as well as several MMA fights, including a heavyweight showdown as former IFL champion Roy Nelson takes on former UFC heavyweight contender Jeff Monson, a teammate of Lashley's at American Top Team.
