From one rematch to another, Marloes Coenen will indeed face a past opponent at Strikeforce on Nov. 7 as Roxanne Modafferi has stepped in to replace Erin Toughill in the women's fight that will remain on the undercard for the show, which could crown the next contender for a shot at champion, Cris "Cyborg" Santos.

The news was confirmed to MMAWeekly.com by sources close to the fight on Thursday. Bout agreements are expected to follow shortly.

Modafferi has been rumored to fight in Strikeforce for sometime now, but makes her debut on just over one week's notice to fight Coenen after an ailing Erin Toughill was forced out of the fight.

An experienced fighter spending most of her time competing in Japan, Modafferi brings a tough background into the fight, and she has faced some of the best competition the women's division has to offer.

As previously stated, Modafferi and Coenen have faced each other in the past. The two squared off in K-Grace 1 in 2007 with Modafferi getting the nod via split decision.

Usually fighting around 135 pounds, Modafferi will go up in weight to face the bigger Coenens, but she has fought many of the top level fighters in the women's division already so it may not play as big of a factor in this bout.

Strikeforce will make their CBS debut on Nov. 7 with the headlining fight pitting Fedor Emelianenko against Brett Rogers in a heavyweight contest.
