Clark is the second Broncos offensive lineman to sign a two-year extension in five days. Seventh-year pro Manny Ramirez signed his deal on Thursday, one week after making his first career start at center.
Clark said this summer that he was preparing as though he'd be the starting left tackle, not just keeping the seat warm for Clady. Playing with the starters,Duke Johnson Jersey, he said, allowed him and Manning to get comfortable working together.
