Jana Kramer has separated from former NFL player Mike Caussin, who she has been married to since 2014.

People reported Caussin has entered rehabilitation for undisclosed treatment. A source close to the singer reportedly said, “This has been diofficult for Jana but her priority is being there for Jolie.”

Jolie is the couple’s seven-month-old daughter.

Caussin has been retired since 2015 after he received a knee injury. Before, he had suffered from a torn ACL and other hip issues.

The couple married after dating for four months and they were married in May 2015 before welcoming their baby girl Jan. 31 this year.

A photo of Caussin last appeared on her Instagram account in July.
