MIAMI GARDENS — Dolphins offensive tackle Terron Armstead, who is presumably battling a right knee injury, isn’t likely to play Sunday at Houston, coach Mike McDaniel said Friday. “I am a little pessimistic about it this week,” McDaniel said of Armstead’s chance to play. If Armstead doesn’t play, he’ll be replaced by rookie Patrick Paul. Armstead, who missed the Tennessee game earlier this season with a concussion, only played five snaps in last week’s 32-26 overtime win against the New York Jets. There were three plays in that game in which Armstead could be seen hopping on his left leg while keeping his right leg off the ground, presumably to keep weight off his right knee.
