Jack McInerney's controversial red card, handed out against the Montreal Impact for his involvement the post-Martin Rivas headbutt 'scrum,' has left a hole at the starting false nine or central advanced forward role in the Philadelphia Union's hybrid 4-3-3.

The Union's options to replace McInerney have little starting experience in Philadelphia colors, but they do provide the team with some attributes not seen on the field otherwise.

Chandler Hoffman - the rookie striker was misused by former head coach Peter Nowak, forced to play a pseudo-winger position in his first appearance for the Union. Since, Hoffman has featured in friendlies and some other playing time and still remains the only striker on the Union whose skillset revolves around poaching goals. He also has size, standing at 6-foot, 1-inch tall.

Antoine Hoppenot - another rookie striker, but this time he's a supplemental draft pick, not a first rounder or Generation Adidas player. Hoppenot has impressed greatly almost whenever he comes into a game as a supersub. The former Princeton University standout was unable to do much in his first and only start of the year, but that was due in part to him and McInerney sharing a similar playing style. He most likely will not start today's game.

Josue Martinez - a former Costa Rican international at only 22-years-old. Martinez has played to mixed reviews so far this season, but his speed, work rate and potential have fans and media still waiting to see what he can bring to the table. This situation could give Martinez the opportunity to break into the the pecking order for substitutions, or even the starting lineup.

Jorge Perlaza - acquired in a trade with the Portland Timbers that sent Danny Mwanga to the west coast. The Colombian has had one opportunity to break into the team and he failed at it. It's a big question as to whether or not interim head coach John Hackworth wanted Perlaza, but now he's stuck with him. It's not likely that Perlaza starts, but given the shortened roster the Union have right now, he may make the bench.

Who would you choose to start today, in place of McInerney?
