Miami Dolphins running back Daniel Thomas and cornerback Vontae Davis -- who are both dealing with hamstring injuries -- were not on the team's charter flight Friday to San Diego, according to NFL.com reporter Jeff Darlington.
Both players were listed as questionable on the Dolphins' injury report Friday.
Thomas, who has been dogged by hamstring injuries, was held out of practice Friday after taking part in a limited portion of Thursday's practice. He missed extended time during training camp and sat out the Dolphins' season opener against the New England Patriots.
When healthy, however, Thomas has lived up to the Dolphins' expectations when they selected the Kansas State tailback in the second round of the 2011 NFL Draft. Thomas leads all rookie rushers with 202 yards on the ground and he's also ranked eighth in the AFC in rushing.
If he doesn't play against the Chargers, newly-acquired Steve Slaton could see his role increase along with Reggie Bush.
Davis was injured in the Dolphins' Week 2 loss to Houston. He took part in a limited portion of practice all week, and the South Florida Sun Sentinel reported that he actually took a few reps with the starters on Thursday after missing last Sunday's 17-16 loss at Cleveland.
The Dolphins listed linebacker Koa Misi (neck) as questionable and ruled out defensive end Tony McDaniel (hand).
