Concerned younger brother Bjorn Helge, a professional with Lillestrom and close confidante, made repeated attempts to contact him with a few consoling words in the aftermath of the 1-1 semi-final, first-leg draw, says the Daily Mail.
Eventually, a text message came back, saying: "I'm not up to talking at the moment. Give me a couple of days, will you?"
Unanswered messages piled up on his mobile phone until he finally replied to 24-year-old Riise Jnr, who said: "I had been trying to get in touch after the game to see how he was.
"Eventually, he sent a text back saying he was so disappointed he didn't want to speak and telling me to try again in a couple of days."
