Tonight on World Series of Fighting 20, Saul Almeida took on Chris Foster in preliminary action. During the second round, Saul looked for a take down and pushed Foster against the cage. Foster stuffed it pretty well, grabbed Saul’s legs, and — despite it being super illegal under the unified rules of MMA — delivered an excellent piledriver. Despite the move, Almeida won the decision. Maybe if Foster went with a “tombstone” version he might have gotten a three count.
