Belfast Giants suffered an overtime defeat in Saturday night's Elite League clash with the Blaze in England.
Noah Clarke put the Giants ahead midway through the second period and Dustin Cameron levelled before Andrew Fournier struck twice for the visitors.
Coventry hit back with goals from Brad Leeb (2) and Mike Schutte but Jeff Mason equalised with eight minute left to send the game into overtime at 4-4.
Leeb netted in the 63rd minute to secure his hat-trick and a Blaze win.
The sides will meet again at the SkyDome Arena on Sunday in the second game of a double-header.
