Super Eagles winger Samuel Kalu has been advised to call it quite on his professional football career over heart-related issue.
Kalu collapsed during Super Eagles' training in Alexandria on Friday, and was swiftly revived before being rushed to the hospital where he has now been certified fit again.
He trained, lightly, with the Super Eagles on Tuesday, but one of the persons who had the responsibility of looking after his career has advised the player to tell doctors the truth about his history of heart problems.
AllNigeriaSoccer quoted Kobi, who is a close confidant of Kalu, as saying the winger's heart-related irregularities was first discovered at AS Trencin while he was undergoing a medical.
"Kalu should open up to the Nigerian Federation and his club doctors to tell the truth about the discovery made during his previous medical tests and not put his life in grave danger for the sake of money," Kobi said to allnigeriasoccer.com.
"When he first arrived in Trencin he actually did not pass the medical tests as doctors found a strange abnormality with his heart and warned about the risk of cardiovascular problems if he played professional football.
"It was heart breaking news for him at the time and he was so nervous about having to go back to Nigeria. After repeated tests, he eventually made the decision to play on and further heart tests were subsequently conducted."
Some footballers have tragically passed away on the pitch after suffering heart attacks and Kalu has been advised not to put his life in danger.
"We have all witnessed players collapse on the pitch and suddenly it’s bad news. In his case he was lucky to have survived this time but it’s likely a warning sign of the same existing heart abnormality which was first discovered by doctors in Slovakia.
"Withholding such critical information from your doctors who are there to take care of your well being is like playing Russian Roulette with your life, It’s a very dangerous game," he concluded.
