Claypool (hamstring) is in line to practice this week, Ray Fittipaldo of the Pittsburgh Post-Gazette reports.
Claypool didn't appear on the Steelers' Week 4 injury report until Thursday when he showed up as a limited participant, but he downgraded to no activity Friday and subsequently was ruled out Saturday. The team opens up Week 5 prep Wednesday, at which point he'll have his first chance to test out the state of his hamstring.
