Andy Johnson gave Fulham an injury scare after helping secure a comfortable 3-1 victory over Amkar Perm in Thursday Europa League play-off.
Johnson struck the opener after just three minutes but was forced from the pitch midway through the second half following an outrageous body-check from Dmitry Belorukov that sent the England striker sprawling.
The incident marred an otherwise successful night for Fulham who established a comfortable lead for the second leg with further goals from Clint Dempsey and Bobby Zamora.
Only three minutes were on the clock when Fulham took the lead through Johnson, though an inspired pass from Zamora was the highlight of the move.
Dempsey put Zamora into space down the left where he delivered a perfect curling ball to the onrushing Johnson who pounced on the simple tap-in.
In a carbon copy of the opening goal, Zamora threaded a long, accurate pass to Johnson but this time defender Belorukov reacted in time and was able to intercept.
Kushev took advantage of confusion in Fulham's defence to produce a sharp save from Mark Schwarzer shortly after the interval.
It was a rare dangerous moment from the Russians, who slipped further behind in the 51st minute following a magnificent strike from Dempsey, who was given too much room on the edge of the area and lashed into the top corner.
New signing Damien Duff entered the fray as a substitute and had an immediate impact, crossing for Erik Nevland to head into the path of Zamora who buried the ball with a blistering shot that gave Narubin no chance.
Vitaliy Grishin then drove home a hard left foot shot to pull one back for Amkar to claim a crucial away goal.
