ESPN's Jeff Dickerson detailed a couple of fights at the Chicago Bears' final open practice of the preseason, starting with one particularly fiery encounter between tight end Martellus Bennett and outside linebacker David Bass.

Defensive lineman Ego Ferguson, outside linebacker Willie Young, offensive tackle Charles Leno and guard Louis Nix were all involved in scuffles on Tuesday, according to ESPN. Nix was one of two players waived after practice to make room for quarterback Zac Dysert and tight end Gannon Sinclair, who were both claimed off waivers.

"You've got guys competing to try to get spots," Fox said, per ESPN. "It is hot. It is coming down to that point where you pick 53, so it's kind of par for the course."
