Shanklin clashed with Blues colleague Gethin Jenkins at a ruck and was replaced by Scarlets centre Jonathan Davies part way through the second half of Wales’ 17-13 victory over the South Sea Islanders.
“Tom has a small fracture to the nasal bone which will limit his involvement in preparations this week and therefore rule him out of selection for the Argentina game,” said Wales team physiotherapist Mark Davies.
“There is a certain amount of swelling there which will take a few days to settle down, but the injury requires no further treatment and he should be back in contention next week.”
The Wales management have asked Ospreys centre Andrew Bishop to join their training camp for the early part of this week to provide cover for Shanklin, although he has not currently been appointed a full squad member.
