NORTON, Mass. – Chad Campbell’s playoff hopes have ended at the Deutsche Bank Championship. He was disqualified for a simple task that slipped his mind — he forgot to register for the tournament.

Much like the formality of signing a scorecard, PGA Tour players must register at a tournament before it begins. Campbell arrived Tuesday evening and practiced all week. He just never signed up.

Campbell opened with a 1-over 72 and would have needed a strong round Saturday to make the cut. At No. 83 in the FedEx Cup standings, he has no chance of making the top 70 to qualify for next week.

This is Campbell’s second administrative blunder. A year ago, he was on the plane to Hawaii for the Sony Open when he realized he never entered the tournament.
