Youssouf Mulumbu is already in the bad books of new West Bromwich Albion manager Steve Clarke.
Clarke, known for his friendly approach as coach at Liverpool, Newcastle, West Ham and Chelsea, may have to exert his authority immediately.
Mulumbu tweeted: "Missed my flight and get blocked in the airport cause of my ID."
He missed the first session of Monday's second training session before returning in this afternoon, says the Daily Star.
