Southampton boss Ronald Koeman will wait for a more accurate date for Fraser Forster 's return before deciding whether an additional goalkeeper must be signed in the summer . Forster underwent knee surgery after falling awkwardly in the 2-0 victory over Burnley a fortnight ago and estimates for his comeback have ranged from four to 12 months . Koeman is reluctant to give a more precise time frame for the England international and views Kelvin Davis as a capable deputy , although he admits he may be forced to bolster his goalkeeping options if Forster 's recovery is delayed . Fraser Forster suffered a serious knee injury in Southampton 's match with Burnley a couple of weeks ago . The England goalkeeper has undergone surgery but will certainly be out for several months . Manager Ronald Koeman would not be drawn on whether Southampton will sign a new keeper in the summer . 'Fraser is down , of course . I spoke to him last week , ' Koeman said at his press conference ahead of Saturday 's Barclays Premier League trip to Everton . 'The operation he had last week went okay , but he will be out for a long time - at least for this season . We have to wait to see how long he will be out for , it 's difficult at this moment . 'Fraser is a fantastic goalkeeper . He was and is the number one for us . But as for every player you need good substitutes for each position . 'Kelvin Davis is a very experienced goalkeeper who played very well against Burnley . Koeman said he will wait for further updates on Forster 's condition before making the decision . Kelvin Davis will deputise for Forster until the end of the season . The Saints still retain an outside chance of making the top four and reaching the Champions League .
