Dolphins wide receiver Brandon Marshall has admitted to making a "boneheaded move" in Thursday night's loss to the Bears. Marshall was flagged for taunting when he tossed the football to Bears quarterback Jay Cutler following a reception. "I let a lot of people down," Marshall said. "We all took our turns in stalling our team, myself included. [I] dropped two balls and got a dumb penalty fooling around with Jay Cutler. That's not acceptable, especially in a game like that. We were all disappointed." Marshall and Cutler were teammates in Denver. "After the game we talked and there's nothing bad there," Marshall said. "That was a boneheaded move by me. It cost our team some yardage and I wish I can have that play back."
