What happened: J.J. McCarthy warmed up in his New York Giants uniform ahead of Sunday's scheduled game against the Arizona Cardinals. The quarterback prepared to debut for the organization following his trade from Minnesota.

Why it matters: McCarthy joins the Giants following a season-ending injury to Jaxson Dart. The newly acquired quarterback opens his New York tenure as a reserve option on the depth chart after the team traded a draft pick to acquire him.

What to watch: The Giants will evaluate their quarterback rotation as McCarthy integrates into the offensive system.
