Melton (knee) is questionable for Sunday's game against the Broncos, Darren Urban of the Cardinals' official site reports.
Melton missed the last two practices of the week while tending to a knee injury, but head coach Mike LaFleur said Friday that the third-year defensive back is "trending in a positive direction" ahead of Sunday's game, per Bo Brack of GoPHNX.com. Kalen King would see more defensive snaps if Melton does not play against Denver.
