Steve Bruce expects that injury plagued midfielder David Dunn will be absent for the rest of the season as Blues attempt to avoid relegation from The Premiership.
The former Blackburn man has started just eight league games this season and his most recent setback occurred in the derby game against Aston Villa on April 16 as he picked up a calf injury.
Since a lengthy absence due to back surgery in January 2005, Dunn has struggled with hamstring and calf problems, and his injury jinx has now persisted as he will miss the upcoming games with Everton, Newcastle and Bolton.
Blues are currently clear of the bottom three due to goal difference, and Bruce was unable to contain his disappointment as he explained Dunn would be unavailable for the remainder of the survival campaign.
"I can't see David playing again this season," lamented Bruce.
"You feel sorry for the lad. When you've only played something like two 90 minutes in two years it does become very difficult.
"There comes a time when whatever you say or do can't help the kid.
"He is a devastated footballer who just wants to play. He will need to be tough."
Dunn's absence comes at a crucial time and Bruce could also be without Jermaine Pennant and Emile Heskey for the trip to Everton on Saturday.
The duo suffered groin and ankle injuries respectively in the crucial 2-1 win over Blackburn Rovers in midweek, and Bruce rates their chances of regaining fitness at 50 percent.
"We will give the two of them as long as possible to try and be fit for Saturday," Bruce added.
"Their chances are around about 50-50."
