Buffalo Bills right guard Ruben Brown is listed as doubtful for Monday night's game in Miami.
Brown has a strained hamstring that could keep him out a week or two. However, Brown would not rule himself out of the game after Wednesday's workout in the Ralph Wilson Fieldhouse. Nevertheless, it's likely Jamie Nails will have to start in Brown's spot.
Meanwhile, defensive end Phil Hansen is questionable with a sore chest muscle, and backup quarterback Rob Johnson is questionable with a mild concussion.
Miami lists starting guard Mark Dixon as out with a sore groin. Running back Cecil Collins and defensive end Kenny Mixon are probable with sore ankles. Safety Shawn Wooden is probable with a sore thumb.
The Bills practiced for about 90 minutes without pads Wednesday. It was an extra day of preparation. They will have full practices today and Friday. During the Marv Levy era, the Bills typically were off Tuesday and Wednesday during the week of a Monday night game.
"It was like a jog tempo," said linebacker Sam Cowart. "We wanted to try to get a head start on things Miami is doing. . . . They had a bye week, so they were a step ahead of us and we wanted to take advantage of everything we can."
