And the reason was (shamelessly stolen from .com) ....
PS: The BBC reported that Kazenga LuaLua had received a first call-up by DR Congo for their two friendly matches this week.
It was thought that the 17 year-old could make his bow either against Gabon in Creteil on Tuesday, or 24 hours later when DR Congo moved on to Paris to face Algeria.
However it's now been confirmed that LuaLua didn't responded to the call-up and remained on Tyneside.
