I am sorry for posting this issue in this forum, but I could not find any e-mail or form post where I can post an issue with the giants.com web site.
It seems that any links in the event calendar which have a forward slash ('/') in the name (e.g. 'RB/TE Autographs') result in a 404 Not Found error when they are clicked on. I believe the issue is the presence of the forward slash in the URL. If the forward slash in the URL is replaced with a dash ('-'), the page resolves as expected.
For instance, the URL for the example above ('RB/TE Autographs') is:
'http://www.giants.com/news-and-blogs/event/RB/TE-Autographs-201308141545/e2631762-225b-4549-8f66-65c50728ba81', which results in a 404 error when browsed to.
If the URL above was changed to this:
'http://www.giants.com/news-and-blogs/event/RB-TE-Autographs-201308141545/e2631762-225b-4549-8f66-65c50728ba81', the proper page is found and loaded.
Please look into correcting this issue.
