The Nets signed Collins to a second 10-day contract Wednesday, and he played 19 minutes later Wednesday night against the Memphis Grizzlies.
Collins became the NBA's first openly gay player when he signed his first deal Feb. 23. Teams can sign players to two 10-day contracts, and then have to sign them for the rest of the season if they want to keep them.
Collins has appeared in all six games since his return. The 13-year veteran played for the Nets from 2001-08.
