DAVIE, Fla. (AP) -- Miami Dolphins rookie running back Daniel Thomas is listed as questionable for Sunday's game at San Diego because of a hamstring injury.
Also questionable are cornerback Vontae Davis, who missed last Sunday's game with a hamstring injury, and linebacker Koa Misi, nursing a neck injury. Davis was limited in practice Friday, while Thomas and Misi sat out.
Ruled out of the game was defensive end Tony McDaniel, sidelined since he broke his right hand in the opener.
Thomas, a bright spot for winless Miami, rushed for 202 yards in the past two games while averaging 4.9 yards per carry. He missed the opener due to his hamstring injury and aggravated it this week.
Thomas' injury could mean playing time for Steve Slaton, claimed off waivers Wednesday.
