The England star has been out of action since suffering a concussion in the clash with Leicester Tigers on September 24.
But he is now progressing well and was able to return to contact training on Saturday, according to Saints boss Phil Dowson.
“Courtney Lawes is working on concussion protocol and he got in touch today so that was really positive,” Dowson said after Saturday’s win over the Newcastle Falcons.
“There’s no rush on it, he takes it at his own pace and the doctors are brilliant at getting through this because it’s obviously a whole new system with a lot of stages.
“If you miss a step you go back but I saw Courts this morning and he was in contact formation so that was good. I believe it was his first contact session.
“Courtney is really good at communicating with me and he knows what’s going on.”
Saints released a statement on Thursday revealing Dan Biggar being assessed for a knee injury following the win at Wasps on Oct. 9.
Biggar will not be available for the Saints for the rest of this month, and his appearance in the Wales autumn internationals remains uncertain.
“Biggs is going to get more expert advice on what that knee looks like,” Dowson said.
“At the moment there are different opinions as to how long it will last, but he takes each day as it comes.
“He’s in a relationship at the moment, but how long will that last, I don’t know.”
The Saints were also without Tommy Freeman and Courtnall Skosan for the game against Newcastle.
“Tommy is in a (protective) boot and that will come off on Monday,” Dowson said. “I think they will X-ray him on Monday.
“We will then have more information.
“Courtnall just showed late (concussion) symptoms (after being taken up in the air at Wasps).
“Maybe it’s nothing, maybe he didn’t drink enough water, but he had a headache so he was out.
“He’s frustrated but it was the right thing to do.”
