Claypool (hamstring) was a limited participant at Thursday's practice, Teresa Varley of the Steelers' official site reports.
Claypool was limited for a second straight practice session as he continues to manage a hamstring injury that sidelined him in Week 4. Friday's final injury report will reveal whether or not Claypool is able to practice fully to close the week and approach Sunday night's contest against the Seahawks minus a Week 6 injury designation.
