ALLEN PARK — Safety James Ihedigbo, who didn’t practice on Thursday due to a back issue, has improved overnight according to coach Jim Caldwell. Ihedigbo was back on the practice field on Friday morning
“Sometimes guys wake up with stuff, it just happens. I don’t know when he did, where, I don’t have a sense. It’s just one of those things,’’ Caldwell said on Friday morning.
— Reggie Bush (ankle) was working with a trainer on the sideline for the second day.
— As expected, Larry Warford and Nick Fairley did not practice. Both have knee injuries.
— Kyle Van Noy only had two defensive snaps in his first game on Sunday in the win over the Dolphins. Caldwell said it depends on the packages on Sunday on how much he’ll play. The coach said his snaps will increase gradually.
— Caldwell on Sunday’s game at the Arizona Cardinals: “Obviously this is the biggest one because it’s the next one and it’s the most important one because it’s the next one and I think our guys understand that.’’
— Captains for Sunday are: Joique Bell, Ndamukong Suh and Julian Stanford on special teams.
