The Hennessy Sports show will be live on ITV4 providing fight fans with another opportunity to see one of British boxing's most exciting talents.
Barker, based at the Hainault gym of TBS promotions trainer Tony Sims, won the Commonwealth title during a 19-fight unbeaten campaign.
Barker plans a route to World title glory starting with his Commonwealth title defence against McDermott which will also double as a final eliminator for Matthew Macklin's British title.
"First things first, and I've got two potentially dangerous domestic fights to take care of before I can leave the British scene behind," he said.
Baker V McDermott headlines an exciting night of boxing at the Watford Coliseum. In the chief support bout, local hope George Hillyard faces Matthew Thirlwall in a scheduled 10-round contest between hard-hitting rivals.
The show also features unbeaten heavyweight Tyson Fury alongside hot prospects Bradley Evans, Steve O'Meara, Steve Barnes and the pro debut of Phill Fury.
