The Manly Warringah Sea Eagles have been dealt another blow with front-rower Brenton Lawrence to undergo surgery on his back later this week.

The surgery will go a long way to ensuring the prop forward will continue to be a force for some time, but will mean a long stint on the sidelines and in rehab.

In other injury news, skipper Jamie Lyon will be assessed again later this week in hope that his groin strain settles and he is able to play this Saturday.

Meanwhile, Feleti Mateo, who was injured in a very awkward tackle in the second half in Wollongong, is awaiting scans on his ankle to assess the extent of the damage. He is likely to miss out on this week’s clash against the Raiders in Albury.

Front rower Josh Starling is facing another month-long spell on the sidelines after re-injuring his same knee in the Round 4 loss to the Dragons. It’s a cruel blow for the young prop, who had done everything to ensure he was fully recovered before taking to the field on Saturday night.

Jorge Taufua's road to recovery is continuing, with the winger set to commence running this week.

Clinton Gutherson is undergoing rehab from his ACL injury that was sustained during the Round 1 loss to Parramatta.

Steve Matai will undergo a fitness test on his shoulder later this week to prove himself before this weekends clash and back up centre Tony Satini is a couple of weeks away from returning from his shoulder injury.

Lastly, Blake Leary remains a week-to-week prospect with his troublesome back but remains hopeful of returning to the field sooner rather than later.
