Shovel, Shuffle, or Shuttle

I heard an sportscaster—I think it was Brent Musberger—say "shuttle pass" tonight. I have heard over many different games, professional grown men, trained in sports announcing, say "shovel pass", "shuffle pass", and "shovel pass". Now I had to know. I did some research, and according to Merriam Webster it is "shovel pass". Maybe you knew this, or maybe you just slurred it together to sound like it could be interpreted as any of them...as I used to.
