Ireland defence coach Andy Farrell says that he's hopeful Jordi Murphy will return to training this week.

The Ulster flanker was called up to the squad mid tournament as a replacement for the injured Jack Conan, only to come off with an apparent rib injury in the victory over Russia.

There were fears that that might be the extent of his campaign, after just 27 minutes of play, but Farrell sounded more positive on Monday.

"He's a lot better than we thought he would be anyway," said Farrell.

"He has shaped up really well. He's very comfortable, and walking around. We expect Jordi to be back training on Thursday.

"We've been told he's going to be available on Thursday, and we select our teams in and around that. So we'll stick to that.

"We're happy with how Jordi has pulled up. He was pretty sore after the game, and after all the medical advice that he's been given he's in great spirits."

The other injury concern from that game against the Russians was Joey Carbery. The Munster out-half was withdrawn from the squad shortly before kick-off.

It was confirmed afterwards that Carbery had received an accidental "stamp" in the warm-up, but Farrell says he was back training on Monday morning.

"He's flying yeah, he's in a great place, the best place I've certainly seen him over the last few weeks.

"He was running around the training ground today like he's got a proper spring in his step. He's in great spirits, and ready to go."
