NEW YORK: NFL receptions leader Antonio Brown and Pittsburgh rushing leader DeAngelo Williams were ruled out on Friday (Saturday in Manila) for Sunday’s playoff game at Denver, putting a huge load on questionable quarterback Ben Roethlisberger. It’s the first time in NFL history a team will be without its top rusher and receiver for a playoff game. Brown has been in treatment for a concussion since being hit in the head by Cincinnati linebacker Vontaze Burfict last weekend, a blow that resulted in a penalty which helped set up the Steelers’ winning field goal. Brown made 136 catches for 1,834 yards and 10 touchdowns this season, enjoying a stellar campaign that included 16 catches for 189 yards and two touchdowns in a comeback victory at Denver — the best receiver showing against the Broncos’ defense all season. Williams, who ran for 907 yards and 11 touchdowns on 200 carries this season and caught 40 passes for 367 yards, will be sidelined by a right foot injury.
