Browns running back Peyton Hillis, who has missed six straight games with a hamstring injury, did well enough in an individual workout on Thursday that coach Pat Shurmur said he might be able to participate on a limited basis in Friday's practice. He has already been ruled out for Sunday's matchup with the Bengals. Hillis, who ran for nearly 1,200 yards last season, hasn't played since being injured Oct. 16 at Oakland.
