Ulster discipline key against Saracens

Chris Henry says Ulster must not concede "silly penalties" in what he expects to be a tight Heineken Cup quarter-final against Saracens on Saturday.

The Ireland Six Nations star knows full well that Saturday's game will be a "big occasion" but he says Ulster's players must not get distracted by all the excitement.

"We must turn up and bring all that passion and energy into the game and channel it the right way," added the flanker.
