Cole Holcomb suffers serious-looking knee injury

Steelers LB Cole Holcomb left in the first half of Thursday night's game against the Titans with a left knee injury. He needed to be carted off. Afterward, play-by-play man Al Michaels called it an injury that didn't need to be shown again. Pittsburgh quickly ruled Holcomb out for the game, and this seems likely to be a season-ender. We'll watch for more details. Kwon Alexander and Elandon Roberts would lead the position if Holcomb is out. Roberts has topped 44% playing time just once through seven games. Alexander has played more, with five games of 54% snap share or more. But he has yet to reach 70% in a game. Alexander looks like the better bet for more playing time while Holcomb is out.
