Automatic removal of links after certain time (plugin?)

Hello,

I’m looking for a plugin or a method to remove links from the links section after they are ‘outdated’.
We’re blogging about cycling and we’d like to present links to a certain race, but say, a week after that race is completed we want the links to automatically disappear from the list of links.
Is it possible to display links for a certain period or is there a plugin that can do this?
Any help is welcome!
