Pontypridd born Parks - who joined the Dragons from Perpignan at the beginning of the season - injured his left knee during the game against the Blues on Boxing Day.
Following a scan at Bupa Hospital, Newport Gwent Dragons physio Dan Martin comments:
"We've had great news regarding Richard's injury. There will be a full recovery without surgery and he should be back within 4-6 weeks if all goes well. Following the report, Richard and is feeling hugely positive about his return. It's a great boost for the New Year."
An upbeat Richard Parks added:
"I'm really looking forward to getting back on the pitch with the boys, especially after the result against the Scarlets on New Years Day. The Team Doctor explained that the first week would be a good indication of the severity of the injury and I'm pleased that after only one week I was able to walk with no problems. All being well, I look to return to the Dragons in around 4 weeks."
