The Knights have suffered a triple injury blow ahead of Saturday's clash with the Cowboys.

Forward Tim Glasby is expected to miss at least one week due to the NRL concussion protocol.

โ€œIn terms of the actual head knock over the weekend, it was not of a serious nature, but due to the amount of head knocks Timโ€™s had over the past few weeks, heโ€™s had two in three games now, as per NRL protocol, heโ€™ll have a stand down period for this weekโ€™s game against the Cows,โ€ club head of of physical performance Balin Cupples told newcastleknights.com.au.

โ€œHeโ€™ll follow up with a concussion specialist in terms of protocol this week.โ€

Additionally, youngsters Beau Fermor (ACL) and Phoenix Crossland (foot) will miss the rest of the season with a knee injury.

โ€œUnfortunately for Beau, itโ€™s probably the worst-case scenario, heโ€™s ruptured his ACL (anterior cruciate ligament),โ€ Cupples said.

In more positive news for the club, James Gavet is expected to return from a hamstring injury to take on North Queensland.

โ€œJimmy had some hamstring tightness all through last week and got through training fine,โ€ Cupples explained.

โ€œWe just thought with the importance of the game we just wanted to have no concerns going into it, hence we gave Jimmy a few extra days to get it right.

โ€œHe came through training over the weekend really strongly and heโ€™ll build back into preparation this week.โ€
