Ciarán Frawley is "knocking on the Ireland door", reckons Leinster senior coach Stuart Lancaster.

The 23-year-old centre was named man of the match as the United Rugby Championship holders dismantled the Scarlets on Saturday night.

That was despite having to leave the field for a head injury assessment in the 49th minute before returning to play for three minutes prior to being permanently replaced for tactical reasons.

Ireland head coach Andy Farrell is due on Wednesday to name a 37-man squad for Tests against Japan (6 November), New Zealand (13 November) and Argentina (21 November) with Frawley's form certainly putting him in the frame.

Farrell held a 50-man training camp last month that included centre options Robbie Henshaw, Bundee Aki, Keith Earls, Chris Farrell, James Hume, Jordan Larmour, Stuart McCloskey, Garry Ringrose and Will Addison, who will miss the upcoming matches due to a broken leg.

"I thought he had great balance to his game, his defence was good, he took on the line well, his distribution was good, he worked very well with Johnny [Sexton] and Garry as well," Lancaster told RTÉ Sport.

"He played well. I’m pleased for him, it’s one of the biggest games he’s played in in terms of personnel, it was a strong Leinster team.

"I always had high hopes for him and certainly a lot of confidence. I think injuries have held him back a little bit in the last 12 months, not major injuries but little niggles here and there.

"But he’s a lot bigger and a lot more athletic than people give him credit for.

"He’s got a very good kicking game, he can play fly-half as well. He’s got that ability to play as a second ball player in the backline.

"It’s just a matter of game time now and getting experience in the big games. He should be knocking on the door for Ireland soon, I would have thought."

Henshaw, who started all three Lions Tests this summer, picked a foot injury and was included Leinster’s bulletin today as "unavailable for selection" for Friday night’s game in Glasgow.

The centre "will take a limited part in training this week as the medics continue to monitor his progress."

Lancaster added: "He’s making really good progress, he’s not a million miles away.

"I think we’re just under three weeks to the Japan game, four weeks to the New Zealand game. He’s definitely making progress towards that.

"Obviously for Ireland he’d be pretty integral.

"He’s a quick healer and because he’s naturally fit you can just slot him back in without too much drama.

"He’s diligent in his training and his game understanding so he’ll be one step ahead there. Everyone is really positive in terms of the November series."
