Wales U20 fly-half Sam Costelow will miss Saturday’s 5th place play-off against England U20 after picking up a broken jaw in the win over New Zealand U20.
The 18-year-old only came off the bench in the 28th minute to replace Max Llewellyn, but departed in the 48th minute after a collision when chasing a Cai Evans chip through with blood clearly pouring from his mouth.
It means the Leicester player only spent the last 24 minutes of the France game in his favoured fly-half position, having started in midfield against Fiji before moving in to cover scrum-half, and not been available against Argentina due to sitting an exam.
However, Costelow will still be eligible for the next two World Rugby U20 Championships and is likely to take over the mantle of the starting Wales U20 fly-half next season when Cai Evans graduates the age grade setup.
In the short-term, Wales U20 are unlikely to call-up a replacement due to the travelling time to South America for just one game, with Tiaan Thomas-Wheeler capable of stepping in at fly-half should Cai Evans pick up a knock.
