Reading: Danny Guthrie, Yakubu and Zat Knight to leave club
Danny Guthrie, Yakubu and Zat Knight are among the players leaving Reading.
Midfielder Guthrie, 28, who arrived from Newcastle in 2012, finished the season on loan at Fulham while ex-Everton striker Yakubu, 32, joined in February after three years abroad.
Goalkeeper Mikkel Andersen, a former trainee who turned professional in 2007, has not been offered a contract.
But the club is in talks with Adam Federici, Alex Pearce, Jem Karacan and Stephen Kelly.
The quartet are out of contract this summer.
Slovenian left-back Jure Travner has also been released, along with young professionals Ryan Edwards, Dan Lincoln, Jonathan Henly, George McLennan and Aleks Gogic.
In a statement on their website, the club added: "As we enter our third year out of the Premier League, the club's owners recognise the need for manager) Steve Clarke to freshen his squad.
"After a period of financial instability and with Financial Fair Play regulations in place, the owners are also making a concerted effort to get back to the sensible wage principles that have long been the club's trademark."
