Western Bulldogs key forward Tom Boyd has been ruled out of the remainder of their Good Friday clash with North Melbourne after an early head clash.

Boyd dropped a mark on the wing midway through the first quarter and collided with Roo Scott Thompson at ground level, and was immediately dazed.

He was taken from the field and assessed for concussion and facial fractures before returning for the final minutes of the first quarter, but did not return after the first break.

Boyd was then ruled out of the match with delayed concussion, after sitting out the entire second quarter.

The premiership forward returned to the bench to watch on from the sidelines, and was sporting a significant bruising on his left eye.

Fellow big man Tom Campbell also left the field for a brief period in the second quarter as well, after having his ankle strapped.
