The Vikings will move to add some depth to their wide receiver corps by signing former Packers receiver Javon Walker today, ESPN is reporting according to sources.

Here is the report by Adam Schefter. We have confirmed Schefter's report, per league sources.

The Vikings worked out Walker on Friday. The Vikings have depth issues at wide receiver with Sidney Rice still on the physically unable to perform list and Percy Harvin suffering from migraines. Rice said last week that it's "up in the air" whether he will be ready by the season opener Sept. 9. Rice said he still feels pain in his injured hip.

Coach Brad Childress said Harvin possibly could return to practice Tuesday after collapsing at practice and being hospitalized overnight late last week. Walker has a history with Brett Favre and offensive coordinator Darrell Bevell from their time together in Green Bay. Walker had his best season with Favre as his quarterback in 2004, catching 89 passes for 1,382 yards and 12 touchdowns. They also had some rough times too. ProFootballTalk.com dug that story up right here. The question becomes, how much does Walker have left in the tank? He played most recently for Oakland and really hasn't done much since the 2006 season.
