Signal processing, I want to remove a specific segment from signal

Hi guys,
I want to remove a specific segment of a signal and replace it with zeros or previous values of signal. I consider this segment as artifact and I want to remove it. The signal is shown in the picture below and the segment I want to remove is the segment between cursors. The position of these unwanted samples in the vector of signal that must be removed and replace with zeros or previous values are 79800 to 80600. The signal continues till 123000 samples.
Can anyone help me? I tried with other solution I find in the forum but when I plot the signal in the time domain the signal get messy..

If the position is fixed, then you can use indexing to set them to zeros
sig; % 123000x1 signal
sig(79800:80600) = 0;

@Anusshree set those indexes to null:
signal(index1 : index2) = [];
