Royals boss Brian McDermott revealed earlier this week that a deal for Pogrebnyak had been struck, and after the player passed his medical the club say they anticipate the deal to be completed in the coming days.
"Reading Football Club has agreed terms with Pavel Pogrebnyak to join the club," read a statement on club website readingfc.co.uk.
"The player has already completed a medical and the deal is now only subject to the player obtaining a UK work permit.
"Reading Football Club anticipate completing the signing within the next seven days."
Pogrebnyak is out of contract this summer and it has been reported the Barclays Premier League new boys have offered him a four-year deal worth around £65,000 a week.
The 28-year-old spent the second half of last season on loan at Fulham from German side Stuttgart, netting six goals in 12 appearances, but rejected the offer of a permanent deal with the Cottagers.
Confirmation of the deal comes a day after Reading secured the signing of midfielder Danny Guthrie on a three-year contract.
The 25-year-old former Newcastle player completed his medical yesterday and will formally complete the move on Sunday.
