Nottingham Forest skipper Paul McKenna hopes to be fit for Saturday's clash with Norwich.
McKenna sat out last weekend's draw at Reading after feeling his hamstring during the warm-up.
"I felt a slight twinge in training on Thursday and when I felt it again during the warm-up it was only sensible I pulled out," he said.
"I hope to be fit to face Norwich but I won't push it if the medical staff aren't 100% confident.
"We've got a two-week international break after the Norwich game and it would be daft to take any unnecessary risks."
