A passerby saw the man on the ground of Market Street near Buchanan Street around 11:45 p.m. and called police.
The man, of unknown age, was taken to a local hospital with injuries considered life threatening.
Earlier that night, a 42-year-old man was stabbed in the neck in South of Market. The victim reportedly knows the assailant, police said.
