According to Spanish daily newspaper Marca Barcelona are currently looking into the possibility of asking permission to make an emergency signing in the form of a centre back.
Despite having received a two-window transfer ban in the summer, for irregularities in their dealings with players under the age of 16. The Catalan giants are hopeful football's international governing body will make an exception due to the circumstances they are under.
Fifa do cater for the possibility of clubs being able to bring players in outside the transfer window in the event of 'long term' injuries, with the Spanish club feeling they fall into that category thanks to their current predicament.
Vermaelen is not expected to be back fit until next May, with the Belgium set to go under the knife this week to resolve a niggling hamstring problem that has plagued him for the larger part of this year.
The defender has yet to make a competitive appearance for the Blaugrana since his £15 million move form Arsenal, with manger Luis Enrique recently being forced to defend his decision to sign a player who has been dubbed injury prone by many media outlets in Spain.

Vermaelen began his career in the famed academy of Dutch giants Ajax, progressing to the first team and becoming a regular for a number of seasons, before going on to sign for Arsenal in 2009.
The 29-year-old is also a full Belgium international, with his last appearance at any level coming in the this year's World Cup against Russia in the group stage of the competition.
Despite his prolonged layoff Barca currently sit second in La Liga on 28 points, only two points behind current leaders Real Madrid. The Catalans have also only conceded six goals so far this season, the lowest in La Liga. Which begs the question why they are currently on the lookout for defensive reinforcements.
Barca currently have the likes of Gerard Pique, Jeremy Mathieu and Marc Bartra to choose from at the heart of their defence, although the former himself has struggled with injury so far this season.
The La Liga giants have in the past been linked with high profile moves for both Thiago Silva and Mats Hummels of PSG and Borussia Dortmund respectively. However both are highly unlikely to join during the half way point of the season considering how highly they are regarded at their current clubs.
Barca may be forced to turn their attentions closer to home, with Aymeric Laporte and Inigo Martinez, two of the brightest young talents to emerge from La Liga in recent years, currently catching the eye.
Due to the financial pressures on both of the Basque country clubs Barca would likely not have to bid high to force through a move. However Enrique has said he will not buy for the sake of it and, with the January transfer window set to open in just over one month's time, it will be interesting to see how this story develops over the coming weeks.
