Goaltending/BI in high school vs. college

[sleebo]

A little embarassed to admit that I don't know the rule on this one, but I thought this would be the best place to go to find out...
My question is...Is it legal according to NCAA rules block a shot and pin it against the backboard if it has already hit the backboard if the ball is still below the height of the rim? I tried searching through the NCAA rule book on this one. I know we would automatically count the bucket if this play happened in a high school game, but I was not sure about college. In discussing this play with others, I heard conflicting opinions. Thanks in advance for your help.
