The Patriots will be without a regular contributor to their receiving corps on Saturday night against Indianapolis.
A Marshall product, the 6-foot-3, 200-pound Dobson hauled in 37 passes for 519 yards and four touchdowns in the regular season. Only Julian Edelman and Danny Amendola were targeted more than Dobson, who had 72 passes thrown his way.
Another rookie receiver, Kenbrell Thompkins, is also listed as questionable for Saturday. He has a hip injury.
Including Dobson and Thompkins, the Patriots have six receivers on the roster. They also have three wideouts on their practice squad.
The only other Patriots player listed as questionable is cornerback Alfonzo Dennard (knee/shoulder). He was limited on Friday, as was Thompkins.
Eight other Patriots are listed as probable, including cornerback Devin McCourty (concussion). McCourty was limited on Friday.
