Aston Villa goalkeeper Emiliano Martinez suffered an injury scare while playing for Argentina on Tuesday - briefly being knocked out after a heavy fall.
The former Arsenal star, playing just his second game for his country in their 2-2 draw against Colombia, went up to claim the ball under a challenge from Everton defender Yerry Mina but landed on his head just before half time.
Martinez received medical attention on the pitch as concern grew for the 28-year-old, and he was eventually stretchered off and replaced with Porto goalkeeper Agustin Marchesin.
