The country singer was injured during a performance on Friday night when a concertgoer threw a can of beer at the stage that struck him in the face.
The incident took place at MulletFest in Niceville, Florida, just as Lynch was finishing up his cover of Garth Brooks's "Friends in Low Places."
"I was walking down the catwalk and wham, out of nowhere this beer can just nailed me in the face," Lynch, 29, tells PEOPLE exclusively, "It was a completely full can and it felt like a baseball had hit me."
While Lynch didn't see who threw the can, fans immediately began pointing the person out and a small brawl ensued, though the perpetrator was not apprehended.

After the set, Lynch was taken to an emergency room where doctors were able to stem the bleeding. He later received stitches, but the "Where It's At" singer says this won't slow him down.
Promoting his upcoming single "Hell of a Night" – which he says takes on a whole new meaning following this incident – Lynch will hit the stage again in Alpharetta, Georgia, on Saturday.
"The moral of the story is don't throw beer cans, period," Lynch tells PEOPLE. "It's not cool. This guy caused an incident that almost ruined a great night. The crowd was insanely loud and supportive and that's why I wanted to finish my show [despite the bleeding]. I didn't want to get off the stage until I had to."
On my way to the hospital for a few stitches, I’ll be okay ... I appreciate all of you. Fyi the guy who hit me with a beer can got away ...— Dustin Lynch (@dustinlynch) October 18, 2014
