Jason Collins has been signed to a 10-day contract with the Brooklyn Nets.

Quoting unnamed sources, ESPN.com reported that Collins “will be in uniform for the Nets against the Los Angeles Lakers on Sunday.”

“The Nets moved quickly to sign Collins to have another big body available against the Lakers,” ESPN.com reported.

Previously the outlet reported that Collins worked out with the team in a private audition in Los Angeles.

“He's in shape,” Nets General Manager Billy King said of the 35-year-old Collins.

The NBA free agent remained unsigned since coming out gay on the cover of Sports Illustrated last year. Collins, a former center with the Washington Wizards, is on track to becoming the first openly gay active player in the NBA.

Brian Ellner of Athlete Ally, a group working to end homophobia in sports, applauded the announcement.

“Today, Jason Collins tore open the last remaining closet in America, and became the first openly gay player to be signed by a team in one of the big four sports,” Ellner said in a statement. “We are especially excited that Jason will be playing in Brooklyn, just like Jackie Robinson, and in a marriage equality state. This is a piece of history, an important point in the continuum toward justice and a moment to celebrate.”
