England number eight Billy Vunipola could be set for an earlier return than expected against Scotland next weekend.
The influential back-row has been sidelined with knee ligament damage for the last three months but is now due to return to action with Saracens in the Premiership this weekend against Newcastle.
Should that be a success then Vunipola could be in contention to play some part against Scotland one week later.
Vunipola’s ball-carrying has been sorely missed by England despite the defending Six Nations champions winning their first three matches of the 2017 tournament.
Vunipola spent time at England training last week and Jones was impressed with his fitness, giving a positive update.
“It’s pretty positive. We’re working with Saracens to see when he’s going to be available to play. We haven’t written off the hope he’ll play in the Six Nations. He’s looking fit,” Jones said.
