Roy Hodgson is hopeful striker Dirk Kuyt will be back sooner rather than later after damaging his shoulder on international duty.
The Liverpool hit-man sustained the injury while attempting an overhead kick in training for Holland and is expected to miss the next month's action.
Hodgson's sides have suffered a spate of shoulder injuries recently and he is surprised to have collected two identical knocks during his short time at Liverpool.
Kuyt is now expected to miss the next six weeks of action, although Hodgson is crossing his fingers he is back sooner.
"You can never really tell with these ACL injuries, sometimes they can be much quicker," said Hodgson.
"It's strange that I've suffered from ACL injuries four times in the past year, two at Fulham with Andy Johnson and Bobby Zamora, and now Pepe Reina and Dirk Kuyt.
"To come across this type of injury four times over the period of a year is unfortunate.
"Bobby, Pepe and Andy recovered quickly so I think Dirk will too, but whether it will take four weeks more or less is difficult for the conditioning people to say. They can only give an estimate."
Meanwhile, Hodgson insists he was not disappointed at failing to bolster his attacking options before the transfer window closed.
The ex-Fulham boss was keen to strengthen his numbers, but felt that there was not enough time following Javier Mascherano's sale to broker the right deal for the club.
Rather than make a panic buy Hodgson is happy giving a chance to the likes of David Ngog and Ryan Babel as back-up options to Fernando Torres rather than bringing in a fresh face.
"I'm not that disappointed not to bring in another striker because I don't think there was a great choice of centre-forwards out there for any of the teams," he continued.
"We didn't see much movement in terms of strikers between the Premier League clubs because I think there are a lot of clubs chasing a very particular type of player.
"It was only after the sale of Mascherano that it would have been possible for me to have the money available to do a transfer at a high enough level.
"The shortage of time bothered me and I would have been concerned we were jumping into something without researching it fully.
"Quite frankly I didn't see the players out there that really excited me to spend the amount of money those players cost.
"I would prefer to put my weight behind David Ngog and Ryan Babel - who has never been given a proper chance at centre-forward - because we have Torres and good players who can play behind a lone striker.
"I will be using these players in some of the games in order to give Fernando the rest he needs and it will be up to them to prove to me there is no need for us to look further than those to players as Fernando Torres' competitors because they are perfectly good enough to do the job.
"They will get their chances and we will see if they take them but I am hoping between now and Christmas we will have ample quality and possibilities to see us through that period."
