Sanders (thigh) will not play in Sunday's preseason game versus the 49ers, ESPN.com reports. Sanders missed Friday's practice with a thigh ailment, which comes after he sat out a few practices at the beginning of this week with a quadriceps injury. Following last week's zero target debut with the Broncos, Sunday represented a fresh opportunity for Sanders to improve his rapport with quarterback Peyton Manning in a game setting. Now, with Sanders ruled out, he'll have to wait another week to make his first catch as a Bronco.
