Nicolas Anelka will miss Chelsea's FA Cup quarter-final at Coventry City on Saturday because of a toe injury while defender Paulo Ferreira will miss the rest of the season because of a cruciate ligament injury he suffered on Thursday.
Michael Essien and Ricardo Carvalho, who have begun their comebacks from long-term injuries by playing for the reserves, will be in the squad as will Ashley Cole, who was arrested and charged with being drunk and disorderly on Thursday morning.
Coventry will be without full-back Daniel Fox, who has an injured knee. Striker Leon Best, who scored Coventry's winner against Blackburn Rovers in the fifth round, has recovered from a throat infection and will wear a mask to protect a fractured cheekbone.
Theo Walcott, who has not played since November because of a shoulder injury, could return to the Arsenal squad for their delayed fifth round tie against Burnley on Sunday. Striker Eduardo could also be in contention after recovering from a hamstring injury.
Kolo Toure (calf) will not play, although William Gallas has recovered from an ankle injury.
Burnley, who knocked Arsenal out of the League Cup in December, will be without defenders Rhys Williams and Michael Duff for the match at the Emirates.
Duff is serving a one-match suspension while Williams, who is on loan from Middlesbrough, has not been given permission to play by his parent club.
Manchester United manager Alex Ferguson said he had no new injury worries before the quarter-final at Fulham but would re-shuffle his squad following Wednesday's 2-1 win at Newcastle United.
Ferguson, who is taking a 20-man squad to Craven Cottage, said: "It certainly helps us to make changes. We played on a tiring pitch at Wembley then we had to travel back home and up to the north-east, which itself can be exhausting."
Everton manager David Moyes is hoping midfielders Tim Cahill, Steven Pienaar and Leon Osman are all fit for their quarter-final against Middlesbrough on Sunday.
All three missed training this week after taking knocks in the 0-0 draw with Blackburn Rovers on Wednesday. Brazilian striker Jo, on loan from Manchester City, is cup-tied.
Sunderland midfielder Teemu Tainio will miss the match against his former club Tottenham Hotspur because of a knee injury. It is the only Premier League game being played on Saturday.
Tottenham manager Harry Redknapp is hoping Ledley King will be back in defence after missing Wednesday's 4-0 win over Middlesbrough.
King, who has an ongoing knee condition, played two matches in six days last week, but Redknapp said: "His problem is he cannot do it on Saturday and midweek."
