A man was arrested Friday for assaulting another man with a golf club over etiquette at a Texas country club.

Michael Plumlee, 27, of Denton, was one of four men putting on the 16th hole at the Indian Greek Golf Course in Carrollton when another group of men hit their ball onto the green at the same time, Carrollton police spokeswoman Jolene DeVito told the Dallas Morning News.

Plumlee threw the ball off the green as the second group was approaching. DeVito told the paper that an argument ensued and that’s when it turned violent.

According to police, witnesses said that Kevin Sivilay hit Plumlee in the back of the head with a golf club. The Dallas Morning News reported that Plumlee fell to the ground and briefly lost consciousness.

Sivilay allegedly continued his assault, hitting Plumlee a couple of more times while he was laying on the ground. According to KTVT-TV, Plumlee broke several ribs and suffered a brain injury.

The 42-year-old was charged with aggravated assault with a deadly weapon and police said more charges could be coming.
