Knox isn't practicing Sunday due to a groin issue, Joe Buscaglia of The Athletic reports.
Knox's absence is also denoted as "vet rest" on the team's injury report, but this is the first word of a groin issue. It's unclear if the veteran tight end's absence from Sunday's practice is precautionary or if he's going to miss additional time. Knox is slated to again cede most of the team's tight end pass-catching work to Dalton Kincaid during the coming campaign.
