Arizona Cardinals quarterback John Skelton will start Sunday against the Cleveland Browns, an league source told ESPN NFL Insider Adam Schefter on Saturday. Skelton's backup was expected to be Richard Bartel as Kevin Kolb continues to recover from a concussion. Kolb had increased his participation in practice late in the week. But the effects left by a knee to the head during a win Sunday against San Francisco will sideline him for at least one game. Source: ESPN.com
