During match simulation, Cumberland attempted to kick the ball but caught the leg of a smothering teammate.
The small forward was in pain and couldn't weight bear, requiring assistance to leave the ground.
Nankervis played down Cumberland's injury while the Tigers were confident he would be OK to face the Lions.
"I missed the last bit of training but I just spoke to him briefly and I think he should be alright," he said.
"We'll find out more this arvo but I think he should be right."
