Dear (Employer),
 
We regret to inform you that (your name here) will not be at work today. We fully understand (your name here) is a valued member of your organization, but on Sunday night (your name here) was a part of another team - one of the passionate, die-hard Eagles fans who helped deliver a crucial victory over the New York Giants. The incredible teamwork was intense and exhilarating, but lasted into the early morning hours. 
 
And even after the late night, we are hard at work on this Monday morning. Our 5-1 record is a great start, but it is just the beginning. In fact, there may be a few more late nights in your employee's future.
 
We apologize in advance.
 
Sincerely,
The Philadelphia Eagles
