With Glen Davis opting to join the Los Angeles Clippers, the Brooklyn Nets will sign free agent center Jason Collins to a 10-day contract and the 35-year-old center will be in uniform against the Los Angeles Lakers on Sunday night according to sources with knowledge of the situation.

The Nets moved quickly to sign Collins to have another big body available against the Lakers. Collins will become the first openly gay active player in North America's four recognized major team sports.

Davis, set to officially become an unrestricted free agent Sunday at 5 p.m. ET if, as expected, he is not claimed off waivers by another team, already informed teams of his decision to join the Clippers, according to sources.

Collins, already in Los Angeles where he had been working out, will meet with the Nets on Sunday before he is expected to sign a 10-day deal according to multiple sources. ESPN.com reported that the Nets quietly auditioned Collins last week in Los Angeles, paving the way toward this historic signing.

Collins hasn't played in an NBA game since April 2013 with the Washington Wizards. He's been working out on his own for months in the L.A. area after failing to earn an invite to training camp from any of the league's 30 teams in the wake of revealing his sexuality some 10 months ago.
