The Cleveland Browns got the first Sunday morning injury watch off to a bad start.
Rubin was listed as questionable this week with a calf injury. Billy Winn likely will get the start in his place.
Rubin's loss is notable for a Browns team moving to a 3-4 defensive scheme and facing a shaky Dolphins offensive line. A stalwart on the inside, Rubin was expected to play a big role in shutting down the Dolphins' run attack.
