Jamie Buhrer has received some positive news with scans this week clearing him of a ruptured ACL.
The nib Newcastle Knights co-captain limped from the field last Saturday after suffering some minor damage to the ligaments of his knee but it is not season ending.
The 28-year-old suffered a meniscal tear which required surgery on Tuesday evening.
Buhrer is expected to be sidelined for six to eight weeks.
Daniel Saifiti breaks silence on foot injury
This means the versatile backrower could be back on the field as soon as Round 19 when the Knights host the Gold Coast at McDonald Jones Stadium.
Meanwhile, the return of centre Nathan Ross has been delayed.
Ross is sidelined with a groin issue which is taking longer than expected to respond to treatment.
The 29-year-old is hopeful of being made available for selection next week.
Finally, Daniel Saifiti is on the road to recovery from a foot injury (Lisfranc) suffered in Round 13's win over Parramatta.

"Halfway through the first half, my foot got caught in an awkward position," Saifiti explained.
"There was a bit of a strain through one of the ligaments. Luckily I don't need surgery.
