MIAMI -- Dolphins left tackle Terron Armstead was ruled out of Sunday's game against the Houston Texans after sustaining a pectoral injury in the first half.
Armstead left the field and walked to the locker room shortly before halftime with the Dolphins up 30-0 and did not return for the beginning of the third quarter. Brandon Shell entered the game in his stead.
The team captain has started all but one game this season but has played through a toe injury that he sustained in Week 1. He missed the Dolphins' game against the Minnesota Vikings in Week 6 after seeing a specialist about the injury.
