The New England Patriots have announced that offensive tackle Nate Solder and wide receiver Kenbrell Thompkins are out of their NFL clash with the Baltimore Ravens.

Solder sustained a concussion in his side's defeat to the Miami Dolphins last Sunday, his second in as many weeks and as a result was limited in practice.

Rookie Thompkins has missed the Patriots' last two matches with a hip injury and has not been deemed fit enough to return against the Ravens.

New England are 10-4 in their season going into the week 16 contest.
