The 28-year-old hasn’t played since the Barbarians match in September, having suffered a serious hamstring tear in pre-season training.
The Carmarthen product made his Scarlets debut 10 years ago and has been a mainstay of the squad ever since.
Jones comes into a much-changed match-day 23 captained for the first time by Tonga international second row Sam Lousi, who makes a welcome return from injury.
Wales international Johnny McNicholl is another to return after a spell on the sidelines. He slots in at full-back in a new-look back three. Tomi Lewis, who impressed off the bench in the Challenge Cup defeat to Edinburgh, is handed the starting jersey on the right wing and the versatile Ioan Nicholas gets the nod on the left.
In the centre, Joe Roberts has been released from Wales duty to partner Eddie James, who returned from injury in the friendly against Exeter Chiefs last weekend.
Jones wears the No. 10 jersey and links up with Archie Hughes, who turned 21 this week.
Up front, Kemsley Mathias is another Six Nations squad member released by Warren Gatland and he packs down in the front row alongside South African Eduan Swart and tight-head Harri O’Connor.
In the second row, Lousi is back after overcoming a calf issue and he partners Alex Craig.
New signing Jarrod Taylor, who arrived this week from the DHL Stormers, goes straight into the starting line-up at blindside flanker. Vaea Fifita continues at eight with Dan Davis at openside.
The bench includes fit-again British and Irish Lions prop Wyn Jones and 18-year-old Wales U20s hooker Harry Thomas, who is in line to make his senior debut. A product of New Dock Stars RFC, Thomas was captain of the Scarlets U18s last season.
