David DeCastro ruled out with ankle injury

PITTSBURGH -- The Pittsburgh Steelers will be without their best offensive lineman in David DeCastro Sunday when they visit the New England Patriots.

DeCastro, a right guard, has been ruled out after not practicing all week because of an ankle injury. Guy Whimper is expected to start in his place in the 4:25 p.m. ET game Sunday at Gillette Stadium.

Starting left guard Ramon Foster remains on track to play after getting knocked out of the Steelers’ 21-18 loss at Oakland with a concussion. Foster is listed as probable, and he will play against the Patriots barring a late setback.

Wide receiver Markus Wheaton (finger) and cornerback Curtis Brown (coach’s decision) have also been ruled out for the Patriots game. All of the other Steelers who are dealing with injuries, including Whimper (knee) and inside linebacker Lawrence Timmons (hand), are listed as probable.
