Melton (concussion) was a limited participant in Thursday's practice, Zach Gershman of the Cardinals' official site reports.
Melton entered concussion protocols following Sunday's 34-28 loss to the Bills. He wasn't able to practice Wednesday, but his limited participation Thursday indicates he's working his way through the league's protocols. Melton's practice participation Friday should provide clarity on his status for Week 2 against the Rams.
