Channing Crowder questionable vs. Bills

DAVIE, Fla. -- Miami Dolphins linebacker Channing Crowder is listed as questionable for Sunday's opener at Buffalo, meaning he's considered 50-50 even though he has been sidelined since Aug. 17 because of a groin injury.

Pro Bowl tackle Jake Long (left knee) and Pro Bowl receiver Brandon Marshall (ankle) were listed as probable. Marshall hasn't missed practice time despite his injury, while Long has been limited.

Crowder again sat out practice on Friday. Tim Dobbins, acquired from San Diego in an offseason trade, would start in place of Crowder.
