Luke Oliver’s injury may force Phil Parkinson to look for more defensive reinforcements during the transfer window.

The giant centre half, City’s most consistent player this season, could face a month on the sidelines with a damaged hamstring.

City will know more on the state of both defenders today but Parkinson admits he may have to push the board to ask for back-up.

“Luke has been outstanding for us but the pitch is heavy, the training ground’s heavy and you’re always susceptible to those injuries,” he said.

“We’re a little bit down to the bare bones defensively so I might have to be speaking to the chairmen again.”
