Chubb was placed on injured reserve, but Stefanski said that he expects him to return at some point this season.
A source told ESPN’s Adam Schefter that doctors believe Chubb will miss about six weeks.

“Knowing Nick, he’s gonna work very hard in rehab. I know that’s hard to see your teammate go down like that; but knowing Nick, he will work his butt off to get back.”
Chubb was injured in the first quarter of Sunday’s 49-38 win over the Dallas Cowboys. He was pass-protecting when defensive lineman Trysten Hill rolled over his knee from behind. Chubb, who entered the weekend fourth in the NFL in rushing, had already run for 43 yards on six carries against Dallas.
The offense didn’t miss a beat without him: Cleveland finished with 307
