Sat out this past week with a "lower leg" injury, if what I understand is correct his injury is similar to that of Kirklands. We will find out this week but as of right now I don't see him playing Saturday.
Myles Garrett Injury: Updates on Texas A&M Star's Leg and Return | Bleacher Report
If Garrett remains on the sideline, Texas A&M's coaching staff will likely use a group of players to fill the void rather than placing the entire burden on a single lineman. Qualen Cunningham and Jarrett Johnson are likely to see the biggest increase in playing time opposite Daeshon Hall.
Ultimately, the Aggies will do their best to replicate Garrett's usual production, but they would sorely miss his presence along the defensive line if he misses more than one week.
