Alabama’s best pass rusher will miss the majority of the season, if not all of it, due to an ACL injury.

Nick Saban announced Monday that Terrell Lewis had surgery to repair a torn ACL, and he’s out indefinitely. Lewis missed most of the 2017 season due to an elbow injury suffered against Florida State, and the Tide’s lack of pass rush was evident.

Lewis was primed for a monster 2018 campaign as one of the defense’s leaders. The 6-foot-5, 256-pound pass rusher has a rare combination of speed and power, and it’s a beautiful collision when it all comes to together. Unfortunately, that may not be until 2019.

Lewis, however, isn’t wasting any time making his comeback. In a video shared by Twitter user Monster Maker, Lewis can be seen raising his leg without the help of trainers.

“Don’t touch it,” he told the trainer. “Watch a master at work.”

With Lewis out, the Tide’s defense will rely heavily on Christian Miller, Jamey Mosley, Chris Allen and Jarez Parks to help fill Lewis’ void.
