Ryan Farquhar scored a treble at last year's Cookstown 100
Ryan Farquhar has been ruled out of the North West 200 and Isle of Man TT Races and could miss the remainder of the season after suffering a broken arm.
The TAS Suzuki rider was to undergo surgery on the injury on Sunday and a specialist will examine a neck injury later in the week.
Farquhar suffered the injury in practising for the Cookstown 100 races on Friday night.
The Dungannon rider collided with another 250cc machine during practice.
