Ronald Koeman spoke to the BBC after Southampton's 2-0 win over Burnley this afternoon, and he believes Fraser Forster's injury is 'looking bad'.
The Saints won thanks to a Shane Long strike and a Jason Shackell own goal, handing them a vital three points in their pursuit of Champions League football.
However, the game was marred by an early injury to goalkeeper Fraser Forster, with the England international carried off on a stretcher after just 14 minutes.
Forster, 27, signed from Celtic last summer, and has been impressive under Koeman this season - but could have had his season ended by today's injury.
Koeman spoke to the BBC after the game, and admitted that whilst Southampton are still waiting for a scan on his injury knee, the initial thoughts are that the former Newcastle trainee could be out for some time.
"Fraser is at hospital and it is looking bad," said Koeman. "We have to wait for the scan. I hope it will be OK for him but the doctor is not positive."
Forster's injury leaves England short of goalkeepers ahead of their upcoming games against Lithuania and Italy later this month.
Meanwhile, Southampton will have to rely upon 38-year-old Kelvin Davis for the remainder of the season, with Artur Boruc out on loan at Bournemouth.
This afternoon was just Davis' 11th appearance in the Premier League for the Saints, and whilst he fared well against Burnley, Southampton have been dealt a huge blow in their quest for a top four spot with Forster's injury.
