A loud scream by an injured Jack Eichel brought a stunning pause to the Sabres' practice Wednesday.

During a power-play, Eichel suffered an apparent injury to his left leg while skating in front of the net. He got tripped up by teammate Zemgus Girgensons and yelled in pain as he crumpled to the ice. As Buffalo teammates immediately waved for an athletic trainer, Eichel writhed in obvious agony. He gripped his leg with a wince on his face.

"I was just trying to get the puck, and we got tangled," Girgensons said in KeyBank Center. "He just fell awkward. It's always tough to see someone go down, especially a guy like Eichs."

Teammates eventually lifted up Eichel, who was unable to put weight on his left leg. The whole group encircled Eichel and glided with him to the doorway to the Sabres' bench, and he disappeared down the hallway.
