It happened around 7:45 p.m. Monday on the 100 block of Sparks Street.
Police say a 27-year-old man was sitting on a couch playing Xbox in his second floor bedroom, when he realized he was shot in the back.
According to investigators, the bullet came through the side wall of the house after traveling a full city block following a shooting nearby at 3rd and Sparks. Police found two cars at that location that had sustained damage after being hit by gunfire as well.
The victim was rushed to Albert Einstein Medical Center where he is in stable condition.
Police say the victim was alone in the home at the time of the shooting.
The man had just celebrated his birthday on Sunday.
No arrests have been made.
