A 26-year-old man from Lincoln was stabbed at an address in the Ermine estate in the city.
It follows a spate of crime in the area.
Lincolnshire Police officers were called to a property on Cabourne Avenue at about 5.50pm on Saturday, August 31.
The man had been injured following an altercation, police said.
He was treated for stab wounds at Queen’s Medical Centre in Nottingham.
Police said on the morning of Sunday, September 1 that he was recovering at home.
Investigations continue today. Officers are asking any witnesses who may have information to come forward.
A spokesperson said: “We would like to interview another man who made off on a pedal cycle following the incident and at this stage we have no description.
“Anyone who was in Cabourne Avenue yesterday afternoon just before ten minutes to five and saw anything suspicious or saw the altercation itself please contact us.”
People can get in touch using the non-emergency 101 number.
Also this week, armed police carried out searches on the Ermine estate and arrested three people, two under suspicion of intent to cause harm and one with possession of a firearm.
It was in response to gun shot noises and smashed windows. No one was injured.
Before this, a man seen carrying a blade was arrested in the St Giles area.
A man was also arrested on suspicion of murder after a man’s death in the Ermine at the beginning of the week. Police have since ruled the death as not suspicious.
