England and Surrey fast bowler Chris Tremlett has undergone back surgery in London, the England & Wales Cricket Board (ECB) has confirmed.
Tremlett had to return home early from England's tour of the United Arab Emirates after a scan revealed a bulging disc in his back.
Chris Tremlett faces a spell of at least three months on the sidelines after specialists recommended that he have an operation on his back. The decision means that he will miss England's two Test matches in Sri Lanka at the end of March and beginning of April, as well as the first month of the county season with Surrey, meaning that he will struggle to be match fit for the start of England's Test summer against West Indies at the end of May.
Graeme Swann and Chris Tremlett are injury doubts for England ahead of their three-day tour game against the Pakistan Cricket Board (PCB) XI which gets underway on 11th January.
The tourists have already lost Tim Bresnan to an elbow injury and his replacement Graham Onions could feature if Swann (thigh) and Tremlett (eye) are not available.
The England and Wales Cricket Board (ECB) have awarded 13 players 12-month central contracts with Tim Bresnan, Eoin Morgan and Chris Tremlett earning such contracts for the first time.
Former One-Day International and Twenty20 International captain Paul Collingwood has not had his contract renewed, however, due to his retirement from Test cricket which makes him ineligible.
Chris Tremlett has been ruled out of fourth and final Test against India at The Oval while Durham fast bowler Graham Onions has been called up to England's squad as cover for James Anderson.
Tremlett has been released from the squad due to the back injury he picked up earlier in the summer, forcing him to sit out the second and third Tests while Anderson has a thigh problem.
England fast bowler Chris Tremlett has been ruled out of the third Test against India at Edgbaston having failed a fitness test due to a back injury.
Tremlett played in England's 196-run win over India in the first Test at Lord's before succumbing to the injury which saw him miss out at Trent Bridge, where England won by 313 runs.
