Leinster head coach Leo Cullen lifted hopes Johnny Sexton will make the Six nations with another positive update on the out-half's fitness on Friday.

Sexton tore the medial ligament in his right knee in the Heineken Champions Cup win over Northampton last month.

On Monday Leinster senior coach Stuart Lancaster said Sexton was on the right path, with Cullen revealing on Friday that the 34-year has started running again in training.  He's still most likely another of couple of weeks away from a return to action, but Sexton's hopes of facing Scotland on 1 February are still alive.

"He's back running now himself and is looking pretty good," Cullen said.

"Next week (against Treviso) is probably a little bit too soon, but he is making good progress."

James Ryan is out of the weekend's Heineken Champions clash at Lyon with a calf problem but Cullen was also upbeat on his condition, adding: "James is okay. We hope he will be back back in the mix next week."
