The 24-year-old striker scored twice in Denmark’s 3-2 defeat in Lviv, Ukraine, on Wednesday as Morten Olsen’s side battled back from a 2-0 deficit but were beaten with a goal three minutes from time.
The source told AFP they were checking if Bendtner broke Article 18.18 of the “Regulations of the UEFA European Football Championship 2010-12”, which states: “All kit items worn during the final tournament must be free of any sponsor advertising.”
That includes: “a) any event held at a stadium, from arrival
at the stadium until departure from the stadium; b) for any training session designated as official by the UEFA
administration; and c) at any official UEFA press conference.”
The waistband of Bendtner’s green and white underwear had the words of a Dublin-based online betting firm.
