Johnson (knee) was listed as a limited participant in Monday's practice estimate, Marcel Louis-Jacques of ESPN.com reports.
Johnson exited Buffalo's Week 1 affair with a knee injury, but it appears he still has a chance to suit up Thursday night against the Dolphins. The 26-year-old running back's practice participation will be something to monitor as the week progresses. If he's unable to go in Week 2, James Cook and Ray Davis are expected to assume all of Buffalo's work in the backfield.
