Pogrebnyak is out of contract at German side Stuttgart and spent the latter half of last season on-loan at Fulham, scoring six goals in 12 games, but opted not to make the move to Craven Cottage permanent.
That paved the way for the newly promoted Royals with manager Brian McDermott confirming earlier this week that the 28-year-old had passed a medical at the Madjeski Stadium.
“Reading Football Club has agreed terms with Pavel Pogrebnyak to join the club,” read a statement on club’s official website.
“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.”
McDermott only requires a work permit before clinching the Russian striker who will be the third free agent to join Reading this summer after Gareth McLeary signed from Nottingham Forest last week was joined by Newcastle United midfielder Danny Guthrie, who signed on Friday.
25-year-old Guthrie left the Magpies after four years after finding first team opportunities hard to come by at St James’ Park failing to displace Cheick Tiote and Yohan Cabaye last season.
The former Bolton and Liverpool man told the club’s official website he didn’t have to think twice before putting pen-to-paper on a three year deal.
“It feels brilliant to have everything agreed, it is a great honour and I am very excited,” he said.
“As soon as I met the manager and Nick Hammond my mind was made up, it was a no-brainer.
“Reading Football Club is a fantastic family club, well run and I’m so excited to be part of something special for this club.”
