Scrimmage kick play question

[CoachLamb]

Hey all. First time poster. I am a coach in Tennessee. We had a play Friday night which left me scratching my head, so I'm hoping you guys can shine some light on it for me with a rule cite.

We are the R in a punt situation. An R player blocks the punt (I actually don't think he blocked it, but the white hat indicated he had a tipped ball). An R player tries to recover the punt beyond the LOS but still short of the line to gain for a first down. K recovers the ball but is still short of the line to gain.

So is it 1st and 10 K from the spot, or 1st and 10 R from the spot?
