|16/1||Tottenham are 16/1 with Bet365 to win the Europa League|
According to a statement from the Football Association, the 23-year-old "reported for duty on Monday with a minor injury and will go back to Tottenham for further treatment".
Townsend, who has six caps, will miss the European Championship Group E qualifier against Slovenia at Wembley on Saturday and the following friendly against Scotland.
The midfielder has struggled to find the form that saw him earn his first England cap last season, as struggles with injury have seen him make just five Premier League appearances so far in 2014-15.
He scored one of the Three Lions' five goals against San Marino in October but has been an unused substitute in their other two qualifying matches.
