Which player has the longest last name in NFL history?

Cincinnati Bengals receiver T.J. Houshmanzadeh

I could make a case for two former NFL players: Runningback Chris Fuamatu-Ma'afala and offensive tackle Greg Robinson-Randall.

My database goes back to 1985 and there are a ton of players who's names are abbreviated in some way (T.J. Houshmandzadeh's name is actually Touraj Houshmandzadeh, Jr.), so there may actually be even longer names.
