Safety Donte Whitner and linebacker Ahmad Brooks are among the San Francisco 49ers appearing in a video for the It Gets Better campaign.

The It Gets Better Project begun by gay rights activist Dan Savage encourages troubled LGBT teens to not cave in to bullies, because life eventually gets better.

The San Francisco 49ers are the first NFL team to record a video for the campaign.

“The San Francisco 49ers are proud to join, to let all LGBT teens know that it gets better,” Whitner says in the 60-second ad. (The video is embedded on this page. Visit our video library for more videos.)

Also appearing in the clip are defensive tackles Ricky Jean Francois and Isaac Sopoaga.

Sean Chapin, who launched a petition asking the team to join the campaign, cheered the ad's release.

“This is a proud day for San Francisco, as two of our professional teams have taken a bold stand against bullying,” Chapin said in a statement. “Let's hope this is only the beginning, and that more NFL and professional sports teams around the country take this opportunity to speak up on behalf of LGBT fans and kids.”
