Steve Bywater says he will be out of action for several months.
David James made a premature return to the bench at Portman Road on Sunday, even though he has yet to play a reserve team game as part of his comeback programme, because of the injury to Steve and the fact that Craig Forrest, who watched the game at his old club, is still out of action due to a recent operation for testicular cancer.
"It happened a couple of days ago in training," says Steve.
"'Cloth foot' Shaka Hislop hit a shot and it made my wrist go back.
"I did save it but got a bit of pain doing so."
Steve, who saw a specialist on Monday morning, is confident of a full recovery, and adds:
"I've had the same before on my right hand so I know what it is about, and I know it will recover all right, it's just that it takes a bit longer than other breaks.
"It will definitely be a few months, about four, before I get back; I will need to rest it but I will overcome it."
As for David replacing him on the bench, he says:
"He is there and, though he hasn't played yet, he has been doing all right in training.
"It's a good job he was back; he wouldn't have been sweating on playing, he'd have done a job."
David plays in the reserves this week, and could be fully fit by the time the international break has finished.
Then there will be an interesting battle for a first team place, though, as Steve says:
"Shaka is playing really well."
