Ross had to leave the NFC semifinal in Dallas on Sunday after his right shoulder twice popped out of its socket. The first-round pick from Texas plans to wear a harness on Sunday.
"If I have to make a tackle with my right shoulder I will," Ross said after practice.
Cornerbacks Sam Madison (stomach) and Kevin Dockery (hip) did not practice, although Madison took part in some individual drills. The starter was sidelined for playoff wins over Tampa Bay and the Cowboys.
The forecast for the title game in Green Bay calls for a game-time temperature of about 4 degrees.
Manning does not intend to wear gloves in the game.
