London made his return to the independent circuit by making his Pro Wrestling Guerrilla (PWG) debut on February 21, 2009, at "Express Written Consent". He wrestled in a six man tag team main event where he and The Young Bucks (Nick and Matt Jackson) defeated The Dynasty (Joey Ryan, Scott Lost and Karl Anderson). He later formed an alliance with Bryan Danielson and Roderick Strong, known as the "Hybrid Dolphins". On January 30, 2010, London re-formed his partnership with Brian Kendrick in PWG and together the two of them defeated the PWG World Tag Team Champions Generation Me in a non-title match.
