RED Rock will return to defend its title at the St Joseph Naililili 7s this weekend.
The MH-sponsored side made a confirmation of their entry in the tournament yesterday.
Event co-ordinator Leca Vunibobo said last year's finalists Police had also confirmed their participation.
He said other big names such as Wardens Green, Wardens Gold, Army Engineers, Police Eastern and Seniboro had also confirmed.
"Ten teams will compete in the one-day under-19 tournament tomorrow (today)," he said.
"And the senior teams will have their competition at the St Joseph Parish compound at Naililili in Rewa on Friday and Saturday.
"$3000 will be at stake and the Fiji Rugby Union has confirmed referees from the Suva Rugby Referees Association will officiate at the games."
Vunibobo said James Bolabiu will officiate in the final of the tournament that is being sponsored by Skaffworks Solutions.
