Why did Messi and his PSG teammates wear Sergio Rico's jersey in last match of season?

Lionel Messi and his PSG teammates wore jerseys with Sergio Rico's name in their last match of 2022-23 season. It was to show support for the PSG goalkeeper, who's admitted to a hospital in a serious condition. Rico was hit by mule cart and runaway horse in Spain last Sunday.
