Bolton 3-4 Tottenham

Fadiga, 29, had an operation in Belgium on Friday after collapsing 48 hours earlier before a match with Tottenham.

A cardiologist said the Senegal international might not play again, but Charles Collymore denied the rumour.

"The cardiologist was not authorised to make that statement. He's been carpeted as he is not Khalilou's surgeon and he did not know the case file," he said.

Collymore said Fadiga would be able to return to Bolton next Monday - and insisted that it was not a career-threatening condition, even though the player had had an automatic defibrillator implanted to try and correct his heart.

"Fitting the defibrillator has been done as a safety measure," he said "(Fadiga's surgeon) Dr Pedro Brugada says there is a tennis player and a marathon runner with this device.

It does not mean the end of Khalilou's career. There are sports people who have had similar procedures."

Collymore admitted that Fadiga would not be able to kick a ball competitively for up to eight weeks.

Fadiga arrived at Bolton last month and was given the all-clear by their medical staff following concerns over surgery in Belgium for an irregular heartbeat.

He signed a deal until the end of the season after spending two weeks training with the club following his release from Inter Milan.

Fadiga is yet to start a game and was due to be on the bench in midweek before he fainted.

Earlier in the week, was warned his collapse was "a serious sign" that his football career should stop.

Fadiga's heart problem forced Italian side Inter to terminate his contract in the summer.

He left the Italian club without a single first-team start to his name after joining them from French side Auxerre at the beginning of the 2003-04 season.

He subsequently joined Bolton and made his debut as a substitute in the 1-0 win over Crystal Palace earlier this month.

Fadiga played a major role when Senegal reached the quarter-finals at the 2002 World Cup finals.
