Manly Warringah Sea Eagles have been struck a cruel blow with injuries following last night’s win over Canberra Raiders at Lottoland.

In devastating news, forwards Kelepi Tanginoa and Curtis Sironen have been ruled out for the rest of the season following results of knee scans taken this morning.

Tanginoa suffered MCL and ACL ruptures to his knee while Sironen has an ACL rupture.

Full-back Tom Trbojevic has a medial ankle sprain and is likely to miss two weeks.

Sea Eagles Coach Trent Barrett said it was disappointing results for Tanginoa and Sironen.

“Both players worked extremely hard in the pre-season and have been very good for us in the first four weeks of the competition,’’ Barrett said.

“We all feel for them. Kelepi and Curtis will have the Club’s full support. It is a big blow to the side but we have plenty of good depth in the forwards, so we will fight on.”
