That's the word according to MMAWeekly:

Recently knocked off his featherweight perch by Mike Brown, Urijah Faber will make a quick turn and get right back in the cage on Jan. 25 at WEC 38. A little more surprising, however, may be whom he will be facing. Sources close to the bout tell MMAWeekly.com that Faber will rematch Jens Pulver at the San Diego event.

Although bout agreements have yet to be signed, sources indicate that both sides have verbally agreed to the rematch. Faber bested Pulver in a five-round war in their original outing on June 1 in Sacramento, Calif.

I must say that this is a do or die fight for Jens Pulver, and I don't really see the outcome being any different than the first encounter. Pulver is in real danger of losing his 3rd fight in a row, which would be 4 out of his last 5. This match up makes sense for a couple of reasons. Obviously it would be beneficial for Faber to win impressively as he did the first time. Also, the event is being held in California which just happens to be Urijah Faber's backyard. The other rumored fight for this card is Jamie Varner defending his LW crown against Donald Cerrone, in what should be a very good fight. Thus far, this card is off to a very nice start.
