Well good thing these plants are very resilient. I think you will be just fine as long as there was still enough of that root left intact. However, there could defiantly be a setback in growth from that.
I had an outdoor plant one time literally split directly in half down the stem. I took egg carton and pulled it back together with rope and tied it back up. Thought it was a for sure dead plant because over a foot of the stem was split directly down the middle. Well, it recovered and that plant grew to over 10 feet tall.
Like I said, I wouldn’t worry about it dying. But it could under perform.
Hope this helps.
