Coach Bruce Arians said Tuesday that Palmer (knee) is "so far" ahead of schedule in his recovery from a torn ACL, NFL.com's Kevin Patra reports. Arians expressed optimism that Palmer would be ready to go for the Cardinals' mandatory minicamp, but given the severity of the injury, it's much more likely the team limits their franchise quarterback's activity until training camp. Even so, it's encouraging to see that Palmer appears on his way to being ready for the start of the 2015 season, after he was on his way to one of the best years of his career before succumbing to the injury.
