West Ham United boss Alan Curbishley amother day of injuries, despite their 5-0 thrashing of Derby.
Nolberto Solano completed the rout with a stunning free-kick.
George McCartney was forced off before the quarter-hour mark with an ankle problem, while Bowyer was playing with a groin injury and Curbishley revealed he will have an operation on Tuesday.
"Fantastic result for us," said Curbishley.
"Lee Bowyer's got to have something done. He was playing with a groin strain. He's got to have an operation on Tuesday.
"We're hopeful Georgie isn't as bad as we think.
He added: "It's the way it's been for the last month or two.
"Everyone's been going on about the injuries, it's there, everyone can see it.
"But it's a little disrespectful to the players who have been playing. They have been picking points up."
Of the game, he said: "I think, today, the first goal was always going to be the vital one and we managed to get it.
"That really settled us down and put Derby on the back foot.
"It's very difficult when you're down the bottom there and you go one down.
"We had opportunities in the first half, perhaps to get the second, and it didn't happen.
"We sat down at half-time and said if we go out and set about this right and we get another one, then we can enjoy it. And that's what happened."
