Six minutes late

In 2013, Denver Broncos football player Elvis Dumervil signed a three-year contract with a pay-cut and then had trouble sending in the paperwork. It arrived at the team headquarters six minutes late.

In those six minutes, his team managers, thinking that Dumervil would not accept the pay-cut, decided to remove him from the team rather than keep him at the higher salary rate. If he had just followed up with his managers, and let them know that he had signed the documents and was in the process of sending them, he would probably still have his job.

Follow up (verb): to follow with something similar, related, or supplementary; to maintain contact with (a person) so as to monitor the effects of earlier activities or treatments; to pursue in an effort to take further action. First known use was in 1767.
