Tranmere boss Ronnie Moore bemoaned the injury to Jean-Louis Akpa Akpro after seeing his side end Brentford's 15-game unbeaten run with a 2-1 win at Griffin Park.
Victory came at a cost for Moore, who lost Akpa Akpro to a suspected broken rib in the second half. The jet-heeled striker was taken to hospital for an X-ray after landing awkwardly when he flew into an aerial challenge.
"It's always the way that the players who get injured are your best ones," Moore joked. "He's just been getting his form back and it's no coincidence that we have been winning games."
Akpa Akpro's pace alongside David Amoo caused the Londoners problems on the break, but it was two errors that handed Tranmere the points. Andy Robinson gave the visitors the lead just before the break, converting from the penalty spot after Harlee Dean had fouled David Amoo in the area.
Brentford hit back when Dean redeemed himself, getting ahead of his marker to glance home Jake Bidwell's near post free-kick.
But Adam McGurk won it when he skipped past two defenders to fire in a low angled drive for the winner in the 66th minute.
It was tough on Uwe Rosler's side who had the clearer-cut chances, with Marcello Trotta and Clayton Donaldson forcing good saves from visiting goalkeeper Owain Fon Williams.
Rosler said: "We made mistakes for both goals and they punished us, but we had 23 efforts on goal to their six and on another day one of the shots that was blocked goes in and you win.
"I'm not panicking, my coaches are not panicking and the players aren't panicking at the run ending because we are not Barcelona.
"We were beaten by a very good side. They were very compact and worked hard. They did their homework, but the second-half performance was very good and we will take that into our next game against Orient when we will have to work our socks off to get a result. I thought we were worth a draw."
