On-loan striker Jon Stead is set to undergo cartilage surgery and has been ruled out for the rest of the season. The former England U21 international is on loan at Coventry City for the remainder of 2009/10.
Stead, who scored twice in nine starts and one sub appearance for the Sky Blues, recently said that he expects to leave Town over the summer.
The 26-year-old, who moved to Portman Road from Sheffield United for £600,000 in the summer of 2008, is contracted to the Blues until the summer of 2011.
Meanwhile, Reading's appeal against Matt Mills's red card during last week's game against Town has failed. The defender will serve a four-match ban having been sent off once before earlier in the season.
Elsewhere, former Blue George O'Callaghan has joined Waterford United, who currently lead the League of Ireland First Division (Irish second tier).
