KSW banner, though never featuring in a tournament, instead fighting individually such opponents as Daniel Tabera and
Matt Lindland. Khalidov made his US debut with
EliteXC on their October 10, 2008
ShoXC card against American
Jason Guida. After almost two hard-fought rounds, Khalidov stopped Guida on the feet with an unanswered torrent of punches. Following the collapse of EliteXC, Khalidov has expressed interest in a hasty return to KSW, as previously outlined by his signing with
ProElite in favor of non-exclusive contract status. Due to a broken hand, Khalidov was unable to return for KSW X on December 12, 2008. Following his recovery, he fought

KSW Light Heavyweight Championship. Khalidov signed a three-fight deal with World Victory Road Sengoku and his first appearance for the promotion was on the November 7th card against Sengoku middleweight champion
Jorge Santiago. Although, the fight was not a title bout, Khalidov defeated Santiago via first-round TKO. A rematch of the bout was held at World Victory Road Presents: Sengoku Raiden Championships 12 on March 7, 2010, for the
Middleweight Championship, which Khalidov lost via controversial unanimous decision. At
