The Philadelphia Union will have their third ever captain soon, as their current one will be on the move.

A trade offer for Califf was acknowledged by the Union brass after today's 3-2 loss to the New York Red Bulls. Head coach Peter Nowak and Sporting Director Diego Gutierrez both mentioned that the Union were mulling over a proposal for Califf.

"We're considering something but as of now we don't have an agreement," Gutierrez told Dave Zeitlin. "Danny Califf is a Union player."

Multiple sources have told the Brotherly Game otherwise, stating that Califf, Union team captain in the 2010 inaugural season and this year, had been traded (originally reported on Twitter at 3:46 p.m. by @BrotherlyGame). Another source informed the Brotherly Game that Califf was not at the stadium today, as well.

The destination for the former United States international was unknown to the sources, but Chivas USA had emerged as a rumored location this weekend.

The rumor about Califf being traded to Chivas USA was originally posted by El Bandito Battalion, an unofficial Union supporters group, on Facebook. El Bandito Battalion later updated their Facebook page with the information that Califf was having a physical done yesterday as part of the trade.

The Brotherly Game was told by a source that Califf had injured his hip and was seeing the trainer about that yesterday, but a physical was still possible given the information from other sources about the official nature of a trade involving Califf.

The only ruled out Major League Soccer team is Vancouver, according to Nowak at today's post-game press conference.

New rumors about the situation have pegged the trade as Califf and third year striker Jack McInerney for Chivas' Juan Pablo Angel, who was rumored to be a possible transfer target for the Union last year.
