This is probably nothing but this could be...
Daryn Colledge is "questionable" for the Bills game due to an "Illness".
"Questionable" is defined as
"Questionable = 50% chance a player will play"
Which leads me to believe there is a chance the doctors hold him out like they held out Brandon Jackson in the past after Jackson couldn't go to sleep at all the night before as he was coughing so bad.
It will be interesting to see if Colledge plays, and if Bulaga gets any playing time at LG and how he does there.
Bishop, hall, Neal and Underwood are also questionable, from a remarks from McCarthy and Neal made it sound like Neal will be out and Wilson and Wynn will be in.
remarks from Nance sounds like he thinks he'll be out as he doesn't know enough of the playbook UNLESS the coaches decide to make a limited package of plays just for him but made it sound unlikely.
