NFL star's domestic violence plea

Former NFL star Chris Johnson, whose sister was killed as a result of domestic violence, explains why he is helping ex-Baltimore Ravens team-mate Ray Rice to rehabilitate himself.

Rice was suspended from the NFL in September 2014 after being caught on camera hitting his girlfriend in a lift, and is now without a team.

Cornerback Chris Johnson, who played with Rice in 2013 and won the Super Bowl, says he is "trying to save this young man" and believes the NFL should be doing more to help Rice get back in the game.
