Mettauer sustained a tear in his MCL in Saturday's preseason game against the Jaguars, Charles Goldman of AtoZSports.com reports.
Head coach Andy Reid told reporters Monday that the tear won't require surgery. It appears Mettauer's injury isn't of the season-ending variety. However, the timeline of his recovery is not yet clear, though he likely won't see the field for the rest of the preseason. Mettauer signed with the Chiefs as an undrafted free agent in May and was competing for a depth spot on the offensive line before the injury.
