The Sydney Roosters are hopeful that five-eighth Luke Keary will overcome a left knee injury as they charge towards the finals.

The 26-year old limped off the field during Sunday's 36-18 win over the Dragons and was sent for scans on suspected medial damage.

But coach Trent Robinson was confident that the injury was not going to be a long-term issue.

โ€œHeโ€™s got the brace on as a precautionary,โ€ Robinson toldย The Daily Telegraph.ย 

โ€œI donโ€™t think itโ€™s anything too bad. But I donโ€™t know how long it will take to turn it around.

โ€œItโ€™s obviously a concern but I donโ€™t think itโ€™s a long-term concern.โ€

Keary is expected to miss at least the team's clash with the Cowboys on Saturday, withย Sean Oโ€™Sullivan andย Ryan Matterson looming as potential replacements.

"I donโ€™t know. I think Iโ€™ve been wrong here before on some players and playing the following week,โ€ Robinson said.

โ€œI felt like he knew it was coming on and he adjusted a bit. When an outside back comes off, itโ€™s usually something wrong. Especially a player like Luke I donโ€™t think heโ€™s come off much at all.โ€
