The Ravens are not worried about defensive tackle Arthur Jones, who is having his best season. However, the Ravens are worried about Jones’ brother, Chandler Jones. He leads the Patriots in sacks with 11½, and with Joe Flacco expected to play on an injured left knee, the last thing the Ravens want is Chandler pressuring Flacco from the blind side.

Blocking Jones will be the primary responsibility of Ravens left tackle Eugene Monroe, who the Ravens entrust to get the job done. However, Jones’ skills stood out this week when coach John Harbaugh studied film.
