The Glasgow Warriors No. 6, who will win his 35th cap, was substituted in the second-half of the 15-15 draw with England in the Calcutta Cup with a head knock.

But Brown has been given an initial thumbs up from the Scotland medical staff although he is due to face further tests before the match.

There are three changes on the bench though with scrum-half Mike Blair and prop Alasdair Dickinson both back after recovering from concussion with Rory Lawson and Geoff Cross making way.

Lock Nathan Hines has a knee injury so misses out with 20-year-old Richie Gray returning in the 22 man squad.
