Tennessee/LSU

[Kirby]

There was a controversial play that was reviewed in the first half (2nd quarter I think).

LSU punted and while the kick was bouncing on about the R-5 it appeared to touch a Tennessee player, a member of the receiving team. The ball then rolled into the endzone. I do not care who thinks the ball was or was not touched by the player. I am wondering what the ruling would be under the NCAA code. In NFHS, this is a touchback the moment the ball crosses the goal line even if the kick is muffed by R.

In NCAA, can a member of R provide a new force (impetus) to a scrimmage kick? At what point is a kick ruled a touchback?
