Can you advance the ball on an onside kick in the NFL?

Answer 1

You can advance your own fumble if the play is still alive, you pick up the fumble in a legal position (off your knees and elbows and not being touched by the opponent) and whistle doesnt sound.

Answer 2

The receiving team can advance the ball once they gain possession. The kicking team cannot advance the ball unless it was first in possession of the receiving team.

There was a rule in College Football where the defense could not advance the ball after recovering a fumble but it was abolished in 1992.
