The Sky Blues boss also revealed that Tudgay, Johnson and Maddison are all major doubts...
Coventry City manager Steven Pressley has revealed that Jim O'Brien is a doubt for tomorrow's game as he is in hospital with his wife who is expecting a child.
Pressley also said that Danny Pugh is set to miss the rest of the season with an injury while Marcus Tudgay is a doubt with a hamstring injury.
The City boss said: "Jim could be a doubt for Saturday's game as he has been with his wife.
"He was at the hospital all of last night but we have no news as it is an ongoing situation.
"You have to be prepared to deal with circumstances like this in football and we have plans to do so.
"We were hoping for good news on Danny Pugh but it's bad news and we think his season is over as he needs an operation.
"Marcus continues to remain a doubt with his hamstring injury, while Reda Johnson and James Maddison are also very doubtful to make it. Aaron Phillips is still injured."
