As I blogged here last year, the team made a huge mistake in letting Chris Pressley leave. Now they are left with Fui Vakapuna (who Pressley beat out last year in Bengals training camp) and rookie free agent Joe Tronzo from Louisville. Third-down back Brian Leonard can also play fullback in a pinch, but that certainly wouldn't be an ideal situation.
There is always a chance the Bengals will find a fullback on the waiver fire at final cuts - but it's not looking good the way it stands. Vakapuna already has a shoulder injury and will miss this Sunday's preseason opener against the Cowboys.
Also out for the Bengals are wide receiver Antonio Bryant (knee), offensive lineman Andre Smith (fat, er, that should say "foot,") linebacker Rashad Jeanty (leg) and safety Tom Nelson (knee).
Hey, you know the Bengals have done a nice job with their roster when fullback is the only clear weakness.
