McCarthy, who has joined the Dragons from Hull KR, suffered the injury just before the holiday break period.
The loose forward is itching to get back on the training field.
“The last day before the holiday period break I was unfortunate enough to tear a hamstring, I made a break on the field and ended up being a bit too fast for myself,” McCarthy told the Dragons website.
“Fortunately it’s now on the mend and it won’t be too long now until I’m back on the field doing full training with the boys.
“At the moment I am in the gym just strengthening-up my glutes and trying to test-out that hamstring on the field and its feeling good so I should be amongst the action in the next week or thereabouts.
“My goal now is to push myself into the picture as best as I can and whilst it’s been a bit frustrating with the injury once I get back out there I will know where I’m at.”
McCarthy has praised the arrival of Jason Demetriou from North Queensland as a new assistant coach at the Dragons. The back-rower played under Demetriou in the Queensland Cup with the Northern Pride.
Demetriou played for Wakefield, Widnes and Keighley and coached Keighley to promotion into the Championship.
“Jason is a fantastic coach who has had a lot of success wherever he’s been including in the UK with Keighley where he took them to a Championship,” McCarthy said.
“I myself played for him during my time with the Northern Pride in the Queensland Cup and we enjoyed a lot of success there.
“Jason also been involved with the Cowboys set-up and it’s on record for everyone to see what happened there.
“He is a very honest bloke who shares a lot of the same traits as all the other coaches here and will complement the Club well.
“He’s very particular with his attacking structures which is what he took hold of during his time at the Cowboys and it is something that I have learnt in regards to shapes and targeting people.
“Jason also has good man-management skills and brings out the best in players and makes them want to play for him, similar to Paul McGregor.”
