Fremantle assistant coach and former star West Coast full-forward Peter Sumich has reportedly pulled out of the race to be the Western Bulldogs' senior coach.

Radio 6PR analyst and News Limited reporter Kim Hagdorn told Mornings with Gary Adshead that Sumich had withdrawn his candidacy because of family reasons.

Sumich has teenage children attending university and high school in Perth.

"Peter Sumich has withdrawn from the race to get the Western Bulldogs job. He's been so determined to become a senior coach and yet he's withdrawn," Hagdorn said.
