Claypool (hamstring) was a full participant in practice Friday and doesn't carry an injury designation into Sunday's game against Seattle, Teresa Varley of the Steelers' official site reports.
Claypool followed the same pattern as last week, when he upgraded to full participation Friday after a limited practice session Thursday. He produced 130 yards and a touchdown against the Broncos on game day, and Claypool is poised for another productive outing Week 6, this time in front of a national audience in primetime against the shaky Seahawks secondary.
