Seahawks activate Paul Richardson, place Ricardo Lockette on IR

The speedy second-year pro could open up Seattle's passing attack and none too soon with the high-flying Cardinals visiting Sunday night.

As expected, the Seahawks officially activated wideout Paul Richardson Saturday, setting him up to make his 2015 debut in Sunday night's showdown with the NFC West division-leading Arizona Cardinals.

To complete the transaction the Seahawks placed Ricardo Lockette on season-ending Injured Reserve.

It is a remarkable recovery for Richardson, who tore his ACL in last year's divisional playoff win over the Carolina Panthers.

While he isn't expected to challenge Doug BaldwinJermaine Kearse or rookie Tyler Lockett in terms of total snaps, don't be surprised if Pete Carroll and offensive coordinator Darrell Bevell had devised a few unique plays over the bye week to take advantage of Richardson's 4.4 speed.

The Cardinals boast one of the NFL's most athletic secondaries but this is a club still looking for a dominant pass rusher. Three players - Frostee RuckerAlex Okafor and the 35-year old Dwight Freeney - currently are tied for the team lead in sacks in Arizona... with two.

As such, Russell Wilson may have the time to take aggressive shots down the field. Doing so, of course, would only open up underneath routes for Jimmy Graham and the running game.

While the addition of Richardson is certainly good news, the Seahawks will have to wait at least another week for cornerback Jeremy Lane, who is still recovering from a torn ACL (and broken arm) of his own.

Lane practiced this week but was not activated Saturday, making him ineligible to play Sunday, per NFL rules.

While Lane has been out the Seahawks have rotated DeShawn SheadMarcus Burley and even star Richard Sherman, at times, at nickel cornerback. Given that this is where Arizona's fastest receiver - John Brown - and most trusted pass-catcher - Larry Fitzgerald - will often line up, how the Seahawks deal with the Cardinals' slot receivers is expected to be one of the keys to this game.
