The headliner for the RBC Canadian Open field will not be playing on the weekend, as Rory McIlroy's week went from bad to worse on Friday, as he followed up his 71 on Thursday with a 78 in the second round to miss the cut by 12 shots.

McIlroy shot an 8-over 78, making a mess of the fifth hole with a quadruple-bogey 8 in his highest score since also shooting 78 last year in the first round of the British Open. He had a double bogey on No. 11, four bogeys and two birdies.

Rory McIlroy made an 8 on his fifth hole Friday at TPC Toronto, free-falling down the RBC Canadian Open leaderboard. After hitting his tee shot into the right rough on the par 4, McIlroy's approach shot from 134 yards traveled 165 — so far past the spectators around the green that they didn't notice it soar over their heads.
