"We're counting on him to be ready. I've got to check with the doctors, but that's what I'm hoping," Carroll told reporters later in the day.
Harvin didn't practice at all last week after being knocked out of Seattle's divisional round win over the New Orleans Saints with a head injury. Carroll said Friday that he expects the pass-catcher to practice this week after playing just 40 snaps all season on the heels of August hip surgery.
Harvin's presence against Denver would amount to a godsend for Seahawks quarterback Russell Wilson, who passed for 200-plus yards for the first time since Christmas in Sunday's NFC title game win over the San Francisco 49ers.
We'll unpack Seattle's matchup with the Broncos every which way over the next two weeks, but there's no bigger X-factor than Harvin. He hasn't contributed much this season, but Percy has a shot to lend a hand in the biggest spot imaginable two Sundays from now.
