Fijian winger Timoci Nagusa has been ruled out of Ulster's Heineken Cup match against the Scarlets tomorrow because of a hamstring injury.

Nagusa was forced to come off during Ulster's win over Connacht and has not been named in the run-on team.

Nagusa's absence will be a dent to the team as he is the club's top try scorer.

The 21 year old winger is the top scorer after he crossed five times in his last three games.

He limped off after 37 minutes of play against Connacht and is replaced by Scotland's Simon Danielli.
