Knox caught his only target for no gain during Sunday's 33-30 win at Las Vegas.
He again played about as many snaps at tight end Sunday (47) as did starter Dalton Kincaid (49), but Knox continued to function mostly as a blocker. He has yet to draw more than three targets in a game this season, and he'll probably remain on the periphery of the passing offense as long as Kincaid is still available.
