Pittsburgh Steelers safety Troy Polamalu practiced for the first time in seven weeks Friday.
However, the seven-time Pro Bowl safety is listed as doubtful for Sunday's game against the Cleveland Browns. Polamalu, who was limited in Friday's practice, hasn't played since Week 5 due to a calf injury.
Wide receiver Antonio Brown is listed as questionable for Sunday's contest. Brown has missed the last two games with an ankle injury.
Fellow wide receiver Jerricho Cotchery has been ruled out after suffering multiple rib fractures in last week's game against Baltimore.
