Do I need to be worried about bighorn sheep?

Maybe a dumb question. Maybe not. Either way, I don’t know the answer. Relatively new to the area. Planning on doing a hike in Boulder City soon. I’m aware that there are a lot of reports bighorn sheep on the trail I’m interested in. As a solo hiker, do I need to be concerned for my safety if I encounter one? Are they likely to cause harm even when unprovoked? Obviously I intend to keep my distance, but if I should accidentally get too close, is that a concern?
