Police were called at arodund 4.25pm yesterday and arrested a boy, 15, on suspicion of wounding.
He was later bailed.
It is the third serious episode of violence in Wolverhampton in the space of just a few days.
Today, DCI Pete Dunn, who is leading the probe into Sunday's stabbings, said it was being treated as an isolated incident.
He said: "It seems that these two men were approached by a group of young men on Francis Street shortly after 4pm on Sunday.
"The young men asked for cigarettes and when their request was refused there was an altercation which ended with the men sustaining knife injuries.
"Neither are critical injuries, however we are still keen to speak to anyone who was in the area as violence such as this unacceptable."
Anyone with information should call Force CID at Bloxwich on 101 or Crimestoppers anonymously on 0800 555 111.
