Wide receiver Danny Amendola sat out practice for a third consecutive day but he was not ruled out for the game against the Buffalo Bills when the Dolphins released their final injury report of the week Friday.
Amendola was listed as doubtful, and Head Coach Adam Gase said his availability for the game would come down to how he handles some running drills Saturday and then pregame warmups.
Along with Amendola, center Travis Swanson also was listed as doubtful. He did not practice Friday after being limited Thursday.
Derby was a full participant in practice Friday after being limited the previous two days, and Parker was limited all week.
The other 12 players who were on the injury report this week will be available. All of them were full participants in practice Friday, except for running back Kenyan Drake (shoulder) and guard Ted Larsen (neck), both of whom were limited.
For Buffalo, guard John Miller (oblique) and quarterback Derek Anderson (concussion) were ruled out, while former Dolphins tight end Charles Clay (hamstring) was listed as questionable.
