Jim D. is correct. The NFL Rule is this:
Rule 4, Sec 3, Article 11
(g) If a fair catch is signalled and made, receivers may choose to extend
the period by one fair-catch down (10-1-6). If the first or third period is
not so extended, the receivers may start the succeding period with a snap
or fair catch kick.
(h) If no fair catch signal is given and the kickers interfere with the
receiver's opportunity to catch a kick, the receiving team may extend the
period by one down from scrimmage. If a fair catch is signaled and the
kickers interfere with the receivers opportunity to catch a kick, the
receiving team may extend the period by either one down from scrimmage
or a fair catch kick.
