Yet another Black Cat went down and then out this past Saturday, as Jan Kirchhoff had to make way early on in the vital 2-1 win at home to Manchester United with a hamstring problem. The German will now be assessed by the club's medical team as they head off to Dubai for some warm weather training.
As well as Kirchhoff's knock during the weekend's game, Duncan Watmore was ruled out just before the clash with an ankle injury, along with Younes Kaboul who has the same issue. Jeremain Lens has also been missing for the last couple of games due to a groin problem.
These players join Sebastian Larsson on the treatment table, with the Swedish international having missed two months with a knee injury; he is showing small signs of progression, having trained again this past week.
However, despite these issues, Allardyce remains hopeful he can have most - if not all - these players available to him by the time Sunderland return to action at his former club West Ham United in two weeks time. Speaking to local media Allardyce said, "The break has come at a good time because of the injuries."
The former Newcastle United manager believes the two weeks gives them a "great opportunity to get people fit", adding "Seb Larsson is making his way back."
The Wearsiders will be using the facilities at Dubai Sports City, which is run by Michel Salgado who played for Allardyce at Blackburn Rovers.
Jermain Defoe's fitness
Another player to come off early on Saturday was striker Jermain Defoe, who was a fitness doubt coming into the game.
However, he did manage 70 minutes and the extended break should keep him available for selection; Allardyce commented on his situation and believes "[Defoe] will be alright", because they "protected" the forward and "brought [Defoe] off early".
The Black Cats boss admitted "the last thing [Sunderland] wanted was [Defoe] pulling up and being out for three to four weeks". This is a sentiment most fans would support, with Defoe being the club's top scorer this season
