Authorities say officers responded to a call for a welfare check in the 9600 block of Halkirk just before 7 p.m.
Deputies say at one point, the man became upset and held a gun to his head. Deputies then contacted the man via cell phone.
Officials say the man then came outside with a shotgun and deputies told him to drop the weapon. Shots were then fired by one deputy, who was 37 years old.
The deputy will be on administrative leave and had been with the agency for five years.
The wounded man was taken to a hospital, where he underwent surgery on his upper torso. The deputy has no reported injuries, according to Gonzalez.
