Eden Park will be at capacity for tonight's Rugby Championship test between the All Blacks and Springboks.

The match has officially sold out, with 48,000 expected at the Auckland ground.

All Blacks fullback Israel Dagg says playing the Boks is the ultimate challenge.

``Love it. Love playing the Springboks. They're a team that really puts you under pressure and they're a team that like to put the back three under pressure so this is probably the biggest I've had for a long time.''

Dagg says there's no point underplaying the significance of the match.

``I'm not saying every other game's not big but this is a huge game. I think the team that wins this is going to have a good opportunity to win the Rugby Championship.''

Rain is expected in Auckland this afternoon.
