Thomas has had a lingering hamstring injury, which seems to be a common trend among the skill positions in the NFL.
Thomas has given Miami a spark in the running game, averaging almost five yards a carry. Thomas leads the team in rushes.
Vontae Davis is also listed as questionable, and had limited participation in practice at the end of the week. Davis missed last week's contest against the Cleveland Browns, which Miami ultimately lost because of a Colt McCoy touchdown pass.
Miami could use Davis' help against the Chargers, for reason none other than covering Vincent Jackson. Philip Rivers and Jackson have developed a nice chemistry, even with Jackson's absence because of a contract holdout last season.
Davis would provide Miami with a huge boost, as the team is on the brink of digging a hole too deep to come out of.
Will Allen, Vernon Carey and Roberto Wallace are all listed as probable, while Vontae Davis, Koa Misi and Daniel Thomas are questionable to play.
Thomas didn't make the trip to San Diego with the team, which means that he is out. While Vontae Davis is listed as questionable, it is unlikely that he will play.
As far as Koa Misi's status, he will probably be able to play. The rest of the players that are listed as probable should be able to take the field Sunday at 4:15.
