The receiver was held out of practice leading up to Chicago's game against the Packers last weekend, but played, catching two passes in the loss.
Marshall was a full participant in practice on Wednesday. On Friday, Marshall said that he used to not be able to jog without pain, which is no longer the case.
"It feels good to go out there and be back with the guys," said Marshall after practice. "I feel like I got my wind back, feel more explosive."
Marshall has 16 catches this season for 144 yards, with five touchdowns. He is a five-time Pro Bowler, including each of the last three years.
The Bears play at the Carolina Panthers on Sunday. Guard Matt Slauson and defensive end Jared Allen are both listed as probable, while center Roberto Garza is questionable. Tackles Jermon Bushrod and Jeremiah Ratliff have both been ruled out.
