Plymouth's win over Hull on Saturday came at a price, as manager Ian Holloway revealed that Paul Wotton picked up what appeared to be a serious knee injury.
The battling 1-0 win over struggling Hull lifted Plymouth to ninth in the Championship, but Holloway feels he could have lost one of his key players for some time.
"Of course the bad news is that Paul Wotton is injured," said Holloway. "He will take some replacing in there.
"He is one of the best professionals I have worked with. It looks long term.
"I said to the lads at half-time: go out and win it for him. They did their job."
Hull are in real trouble in the relegation zone, but caretaker chief Phil Brown felt there were positives to take from the defeat in Devon.
"If the players continue to show the commitment they showed today then it will certainly give me a better chance of becoming the next manager," said Brown.
"I understand we are in the results business and if I can buy the chairman a bit of time of making the right decision about the next manager then that's my job done.
"If I do that it will mean we are winning games and give me a better chance.
"I am quite positive. The players showed a level of commitment that I was satisfied with in a very difficult week for everybody involved at the club."
