UFL Announces Officials and Explains Rules Differences for 2010 Season | UFL

They have added Sarah Thomas who worked the Little Caesars Pizza Bowl last year.

No doubt they are grooming her for the NFL.

Hard to tell without the exact wording (which I suppose must exist somewhere but not linked), but are they saying that in the UFL, opp'ty to make a [fair] catch of an opponent's kick doesn't end until the ball touches the ground or comes into player possession?

Yes. That is consistent with the NFL rule.

Yes. I think what they're getting is if a fair catch is signaled, and the catch attempt is bobbled into the air, the opp'ty to catch the ball unhindered remains.

Bobbled, or we prefer the term muffed.

Huh. So if R1 muffs the ball in the air and K1 plays the ball, it's interference?

I have the 09 NFL book and I don't see anything that results in a foul if K1 plays the ball after an R1 FC muff.

It will at the very least be a COP, and if K1 fumbles, R can advance.

That's also the interpretation in NCAA IF the B team player called for a fair catch.

NFL Rule 10, Section 2, Article 2

Item 3: Muff. After a valid fair catch signal, the opportunity to catch a kick does not end if the ball is muffed. The player who signaled for a fair catch must have a reasonable opportunity to catch the muffed ball before it hits the ground without interference by members of the kicking team, and regardless of whether the ball strikes another player or an official.

The penalty would be for interfering with a fair catch after a signal

Not looking hard enough then. Same in NFL and NCAA - not sure the rule number right now, as I'm at work. But it's there. I promise.

Have the NFL rule right above you haha :D

Also, here's the exact play that happened during week 2 of the past NFL season.

My bad. I was looking for a personal foul, rather than interference.

Darn 2am reading. ;)

NFL Rule 3, Definitions,Section 9: A Fair Catch is an unhindered catch by any player of the receivers of a free kick or of a scrimmage kick except one that has not crossed the line of scrimmage providing he has legally signalled his intention of attempting such a catch.

Rule 10, Section 1, Opportunity to Catch a Kick, Article 1: During a scrimmage kick that crosses the line of scrimmage, or during a free kick, members of the kicking team are prohibited from interfering with any receiver making an attempt to catch the airborne kick, or from obstructing or hindering his path to the airborne kick, and regardless of whether any signal is given.

Rule 10, Section 2, Fair Catch, Article 2, Item 3: Muff. After a valid fair catch signal, the opportunity to catch a kick does not end if the ball is muffed. The player who signalled for a fair catch must have reasonable opportunity to catch the muffed ball before it hits the ground without interference by members of the kicking team, and whether the ball strikes another player or an official.

Quick answer, the receiver must be given an opportunity to complete the catch even if it is muffed. If not, it is interference
