(AP) — A construction worker in Lincoln has been hospitalized after receiving some kind of shock while on the job.

The man was doing directional drilling Tuesday morning on the city’s northwest side when the incident occurred.

The worker was not seriously injured. Authorities are trying to determine if he was electrocuted or exposed to an arc flash.

Lincoln Electric System says the incident created a brief power outage for about 2,000 customers.

Authorities have not released the worker’s name.
