The Patriots have announced that CB Ras-I Dowling has been placed on season-ending injured reserve.
Dowling injured a thigh last week against the Jets and had already been declared out for Sunday's game with the Rams, but now he won't be playing again this year.
He played in six of the first seven games (he was a healthy scratch against Arizona), with seven total tackles and a pass break-up against the Jets.
A second-round pick last year, Dowling started the first two games of his rookie season before being placed on IR with a hip injury.
New England will have to make a corresponding roster move to fill the spot opened by the move with Dowling, but there has not yet been an announcement.
