Chip Kelly said Wednesday that quarterback Michael Vick remains limited in practice with the hamstring Vick reinjured 10 days ago. Kelly said Vick remains limited in practice and isn't able to do even 7-on-7 work yet, as he tries to overcome a twice-strained left hamstring. At this point, you have to wonder if letting Vick heal through the bye wouldn't be the best course. He said defensive lineman Cedric Thornton, who did not practice Wednesday with a knee problem, is scheduled to practice today, and that the same holds true for corner Bradley Fletcher who has been limited in practice this week. Kelly also said the Eagles are not ready to move away from Damaris Johnson as their primary returner, even though DeSean Jackson's punt returning and Brandon Boykin's kickoff returning in Johnson's place against Oakland were more dynamic than what the Birds have been getting from Johnson.
