The Brooklyn Nets on Sunday signed Jason Collins to a 10-day contract, nearly 10 months after he came out gay on the cover of Sports Illustrated.

“RT to welcome @JasonCollins34 to Brooklyn! #Nets,” the Brooklyn Nets tweeted along with a picture of Collins signing his contract with head coach Jason Kidd.

Collins debuted for the Nets in Sunday's game against the Los Angeles Lakers.

“Right now I'm focusing on trying to learn the plays, learning the coverages and the game and the assignments. So I didn't have time to really think about history,” Collins told reporters before the game.

“Jason told us that his goal was to earn another contract with an NBA team,” NBA Commissioner Adam Silver said in a statement. “Today, I want to commend him on achieving his goal. I know everyone in the NBA family is excited for him and proud that our league fosters an inclusive and respectful environment.”

Michael Sam, the 24-year-old NFL prospect who came out gay earlier this month, added his support.

“Congratulations to my friend @JasonCollins34 – excited to see you do work out there #courage #groundbreaking,” Sam tweeted.

Robbie Rogers, major league soccer's first openly gay player, added: “Very excited to watch @JasonCollins34 tonight more importantly I am proud to call him my friend.”
