Michael Carrick is hoping he will not be pressed into emergency service in defence for Manchester United's game against Bolton Wanderers on Saturday.
United's defensive injury problems worsened on Tuesday night after John O'Shea and Rafael were both forced off in the UEFA Champions League win over Marseille.
Nemanja Vidic missed that game due to a calf injury, while his fellow centre-half Rio Ferdinand has been sidelined since the start of February.
The latest injuries have left United with only four fit defenders to choose from, although Northern Ireland international Jonny Evans has a chance of being available to face Bolton.
Carrick was forced to play at centre-half in a 3-0 defeat against Fulham in the Premier League last season and is keen to avoid a repeat scenario.
"It did get a mention in the changing room," the England midfielder told MUTV.
"I said to Mike Phelan 'I don't fancy that again'.
"It is never nice to get the injuries of course. It is disappointing when you pick up a number in a similar position.
"But I don't think we are that desperate yet and hopefully I won't be called upon."
