Ireland will be taking no chances with Ulster centre, Luke Marshall after he took another blow to the head during the first Test against Argentina.
Although there is no evidence of concussion, given Marshall’s past history of similar injuries, he is likely to miss this weekend’s second Test as Ireland look to complete 2-0 series win.
Tries from Chris Henry and Andrew Trimble helped Ireland to a 29-17 win over the Pumas.
But it also came at a heavy prices with halfbacks, Conor Murray and Jonathan Sexton, joining Marshall on the doubtful list for Saturday’s second Test in Tucuman.
Team manager Mick Kearney said there was no evidence of concussion in Marshall but that he would be monitored closely given his history of suffering similar injuries.
The 23-year old Ulsterman was clattered in a tackle while winning his sixth cap on Saturday and had to go off after 57 minutes.
Kearney said: “Luke Marshall was removed as a precaution as he may have taken a blow to the head during the game. Testing came back as normal and his computerised neurocognitive testing was normal as well.
“As such there is no formal evidence of concussion but given his history we’ll be taking every precaution necessary and he will be reassessed on a daily basis.
“Conor Murray suffered a dead leg but is responding well. He will be assessed as the week goes on and is unlikely to train in the early part of the week.
“Jonny Sexton suffered a cramp at the back of his knee and has recovered well and is expected to train fully.
“We came through the game very well. Most of the players actually hadn’t played for three weeks. So we probably went in just a little bit undercooked in terms of game time and that.
“But they came through it really well, from an injury profile point of view it was actually a good outcome as well.”
The Irish squad returned to Buenos Aires from Resistencia on Sunday and will spend two nights in the capital before heading back north for the concluding test in Tucuman.
Kearney said they were pleased with Saturday’s first-ever win on Argentinian soil but feels there is still room for improvement.
“The set-piece was very strong,” he added. “The scrum was good, 14 line-outs won out of 14 and we pinched a few of theirs as well.
“We were a little bit sloppy in defence and they made a few line-breaks. A few handling errors as well.
“I think it was probably a little bit of a mixed bag”
