Bristol City striker Nicky Maynard will undergo surgery on Wednesday on the troublesome knee problem that has kept him on the sidelines throughout the summer.
Last season's 21-goal top scorer could now be out for up to two months.
The news comes on the back of a bad night for the Robins after they were knocked out of the Carling Cup by Southend in the first round.
"Nicky will have an operation today (Wednesday)," confirmed manager Steve Coppell.
"The specialist has found a problem and recommended surgery but we will not know the full extent of the problem until he goes into the knee to see what is there.
"We are hoping it is not too serious and that it will be a case of four to five weeks before he is able to train."
