Manly hitman Martin Taupau needs to tackle his shoulder charge issues to ensure he stays on the field this NRL season, says coach Trent Barrett.

Taupau, along with fellow forward Addin Fonua-Blake, will miss the team’s next two matches for no-arms hits in their round-one defeat to Parramatta last week.

“You can’t shoulder charge. That’s something that Marty and Addin have got to address in their games because they’re too important for us to miss,” Barrett said on Friday.
