Did they comment on it? What hazard?
#8 hole in front of the green - lateral hazard - Nobilo said the player is allowed to touch the top of the grass - but it appeared that Folwer drops the club into the grass when addressing it. Rickie was able to get up and down on the hole. Rolfing and Nobilo didn't say a word about a possible infraction.
That's not a penalty. You can touch the grass you just can't sole your club or touch water. The grass is not a loose impediment either.
