Adam Drury is out with an ankle injury while Alex Notman and Paul McVeigh (both hamstring) will be having late fitness tests tomorrow.
Worthington confirmed, "Paul and Alex both have tight hamstrings and if there is any risk to them I will not play them in the Chelsea tie. We have an important game against Millwall this Sunday and I won't gamble on their fitness.
"McGovern has a chest infection and is on medication, so we will see how he is in the morning. There is no point harping on about the injury situation, no matter what team we put out I hope we go there and put on a good performance."
Talking about the first Chelsea tie he said, "I just wish we had taken one of those four or five chances we had in the Carrow Road game when their keeper got a hand to everything.
"It's obviously good financially for the club to have this tie but it would have been nice to have a week to prepare for the Millwall game and clear up a few of the injuries."
Other recent additions to the injury list have been young striker Danny Bloomfield, who is expected to be out for 4-5 weeks, and Brian McGovern with a cold/chest infection, who might have been drafted in to cover for Drury tomorrow, had he been fit.
With Iwan Roberts (knee), Phil Mulryne (ankle), Gaetano Giallanza (knee), Neil Emblen (hamstring) and Zema Abbey (knee) also on the injury list the need for forward cover is evident - that's four strikers out injured, plus David Nielsen can't play either as he's ineligible, not having registered in time.
This is the team we fielded against Man City: Green, Drury, Mackay, Fleming, Kenton, Nedergaard, McVeigh, Holt, Russell, Notman, Nielsen. Subs: Chrichton, Sutch, Libbra, Easton, Rivers.
... and these are all the players in the first team squad that we have to chose from for the Chelsea game, if Notman and McVeigh fail their fitness tests: Green, Kenton, Mackay, Fleming, Nedergaard, Easton, Holt, Russell, Rivers, Libbra, Chrichton, Sutch, Blois, Llewellyn, Henderson. That's not even enough to make up five subs, even including Blois and Henderson!!
Dear me talk about crisis. How on earth is this team meant to beat Chelsea at Stamford Bridge!
