Did I miss something on the punt return Monday night?

[tklongball]

If I remember correctly, there was a punt in the 2nd half, and Austin received it at the 30, and ended up going out of bounds at the 34. There was a penalty (I believe holding), against us, and after the break we got the ball on the 13 yard line. I couldn't figure out how the hell that happened.

Obviously, it had no bearing on the game, I am only asking out of curiosity, What did I miss?

So the holding probably happened on the 23 yard line. 10 yards from the spot of the foul = 13 yard line.

The Niners punted twice in the first half with no penalties by the Rams.

I think you are referring to this play.
