Assistant coach Alan Dickens is hopeful that George North will be able to play a part in Saints’ Premiership run-in.
The Wales wing saw a specialist earlier this month after being knocked unconscious in the win against Wasps on March 27.
He was told to rest until the end of April, when he will be reassessed.
North will not be involved against Saracens on Saturday, but his club then have a rest weekend before finishing the Aviva Premiership regular season with games against London Welsh and Leicester.
And North will hope to get involved before the semi-final play-offs on May 23.
“Next week we’ve got the week off with it being European final week so that gives him extra time to hopefully improve,” said Dickens.
“He’s on the bike, low level excercise and then we’ll see how he comes through that.”
Harlequins full-back Mike Brown was this week ruled out for the rest of the season due to concussion headaches which have been prompted by a knock-out blow in England’s Six Nations clash with Italy on February 14.
But though Saints will not rush North back, they are refusing to rule out the possibility of him playing again this season.
“In terms of Mike Brown, I don’t know the ins and outs of that, but with George we’ve not got
to that point yet,” said Dickens.
“George is taking part in team meetings, he’s done clips for this week and he’s looking to fill his day so he’s still heavily involved with what goes on in and behind the scenes.
“All of theplayers come in and get screened to see how they are physically and then decisions are made.”
