There are any number of ways to fix this. I prefer a somewhat "quick and dirty" method. That method will work up to a certain size. The bigger the print or web-pixel size, the more accurate you'll need to get, otherwise it will be easy to spot the corrective work.
Would you consider this an improvement? See image below.
If so, I can tell you what I did. It was a simple matter of two layers, clone, erase and dodge. It took maybe 1 minute of work at most. Downloading the photo and opening Photoshop took longer than the work itself, at least for me. (Photoshop user for 15+ years now.)
