What does it look like? If its just lettering or something with stiching, I would just remove it and take it to a seamstress.

It used to not be possible to get an extra pocket cover but last year some club pro shops with authorized Titleist accounts were able to get replacements for current year models. You might try that but no guarantee that they will fit. I have a couple of Players 4 Carbon bags from past years that look Identical but when I try to swap the pocket covers, the zippers just don't match and they do not zip back together.
