Crosby was placed on the list last week. The list was created for players who either test positive for COVID-19 or have been in close contact with an infected person.
He was removed on Friday and took part in his first practice.
Crosby is being counted on to contribute much more after recording 10 sacks as a rookie. He is slated to be a starting defensive end and is the top pass rusher on a team that has struggled to generate consistent pressure in recent years.
