Detroit Lions tight end Joseph Fauria didn’t injure his left ankle on the field during a game or practice. It happened in his apartment while … chasing his puppy.

Fauria offered full disclosure this week about the mishap that resulted in a sprained ankle and left him on crutches.

As Fauria was chasing his 3-month-old Pomeranian-Husky mix down the stairs last Wednesday in attempt to keep the puppy from relieving himself, he missed some steps and landed awkwardly on his left foot.

“He was about to pee and I was like, ‘Come here you little … nugget,'” Fauria said in recounting the incident. “And I was chasing him downstairs. I wasn’t running, but I was chasing him downstairs and I just misstepped and I reached with my left foot and I just didn’t end up well.”

Unable to reach teammate Sam Martin or Lions trainers after the accident, Fauria had neighbors drive him to an urgent care and then to a hospital for an exam.

“It was kind of agonizing pain,” Fauria said.

Fauria refused to discuss when he will be able to return. He has three catches for 49 yards this season.
