Jason Collins marches in Boston gay pride parade

BOSTON NBA veteran Jason Collins has marched in Boston's gay pride parade with Massachusetts Congressman Joe Kennedy III, his onetime roommate at Stanford University.

Collins wore a T-shirt that read (hash)BeTrue when he joined thousands of marchers Saturday.

• Jason Collins: Support since coming out "incredible"
• NBA center Jason Collins: I'm gay
• Collins' major challenge: Finding an NBA team

In April, Collins became the first active player in one of the four major U.S. professional sports leagues to come out as gay. He wrote in an article for Sports Illustrated that the decision to go public came when Kennedy marched in last year's parade and Collins didn't feel that he could join him.

Collins also said the Boston Marathon bombing reinforced the notion that things can change in an instant, so he might as well live truthfully.

Collins played for six teams in 12 seasons and becomes a free agent next month.
