Dolphins RB Malcolm Brown will be placed on IR with a quad injury suffered in Sunday's loss to the Falcons, HC Brian Flores said Monday. Brown will be out at least the next 3 weeks vs. the Bills, Texans and Ravens. He's played 28% of Miami's offensive snaps and averaged 4.7 carries and .7 targets per game, so his absence leaves behind a little extra work for RBs Myles Gaskin and Salvon Ahmed.
