Critics have said Ferdinand has been dropped because of tensions with fellow central defender John Terry [ Images ], who has been picked but faces a court case next month after being charged with racially abusing Ferdinand's brother Anton.
The Chelsea [ Images ] captain has pleaded not guilty over the alleged incident in a match against Queens Park Rangers.
"From afar, I do not think it was a decision based on sport," Blanc said ahead of his side meeting England in their Group D opener on Monday.
Blanc, who played with injury-prone Ferdinand for Manchester United [ Images ] in 2002/03, said the decision to omit him was "surprising".
