Eagles coach Andy Reid revealed following Thursday night's preseason opener that Jeremy Maclin is dealing with a strained hamstring. Maclin suffered the injury in pre-game warmups and was a late scratch for Thursday's exhibition opener. The severity of the strain is unknown, but hamstrings are tricky and can cost players a significant amount of time if setbacks occur. Look for the Eagles to proceed cautiously with Maclin. They are counting on him to be their No. 1 receiver this season.
