Excellent work, Nice Design que es el prozac y para que sirve DE Justin Tuck did not practice Wednesday because of a tight back. “Just taking the precautions,” said coach Tom Coughlin. The Giants moved first-team DT Cullen Jenkins to DE, and slotted Shaun Rogers in at DT. When asked if Tuck will play Saturday in Pittsburgh, Coughlin said he “would expect that to be the case, but he will have to do a little bit of improving.” OL James Brewer (concussion), S Cooper Taylor (hamstring) and RB Ryan Torain (concussion) did not practice. Brewer and Taylor have already been ruled out for Saturday . . . Coughlin said rookie OL Justin Pugh (concussion) could be cleared for next week.
