Arizona Cardinals defensive tackle Darnell Dockett, running back LaRod Stephens-Howling and tight ends Todd Heap and Jim Dray are all listed as doubtful for Sunday's game against the Dolphins.
Dockett left last Sunday's game against the Eagles with a hamstring injury, which held him out of practice this week.
Heap, who missed last week's game with a knee injury, was also held out of practice this week.
Quarterback John Skelton and safety Adrian Wilson are listed as questionable.
Skelton has been out of action since suffering a sprained ankle in Week 1, while Wilson missed last week's game with injuries to his ankle and groin.
