Flanker Lydiate was sorely missed during Wales' autumn internationals where they suffered four straight defeats and Dragons boss Darren Edwards admits he wouldn't be surprised if Howley throws the 2012 RBS 6 Nations Player of the Tournament straight back into international action.
"He is on course for the start of February," Edwards told Wales Online.
"It wouldn't surprise me if Dan has a half of rugby for us and Wales throw him straight in. He's that important - we saw how much he was missed during the autumn internationals."
Wales will already be without Rhys Priestland for the Six Nations and they are also waiting on Ashley Beck's fitness after the Ospreys centre limped off against the Dragons on New Year's Eve.
