Remove line object from the image

I must remove this red part from the image. How can I do that in MATLAB, anyone has ideas? Please help :)

Select the part manually...and fill the values? Did you try this?

I = imread('wrong_part.jpg') ;
[J,rect] = imcrop(I) ;  % select the part you want to remove when image pops

x0 = round(rect(1)) ; x1 = x0+round(rect(3)) ;
y0 = round(rect(2)) ; y1 = y0+round(rect(4)) ;

x = x0:x1 ;
y = y0:y1 ;
[X,Y] = meshgrid(y,x) ;

I(X,Y,:) = 0 ;
