ALLEN PARK — Lions’ Calvin Johnson, who has an ankle injury sustained in Sunday’s win, missed his second straight practice today (Thursday).

“Anytime that someone doesn’t practice, in particular when it’s not just a day of rest which we would indicate on the medical report, there’s always some concern,’’ coach Caldwell said before practice.

— Lions tight end Joe Fauria twisted his ankle away from the practice facility on Wednesday night and will not practice Thursday. 

Coach Jim Caldwell made the announcement in his pre-practice press conference. I said it was an “innocent” thing around the house and mis-stepped.

Caldwell said Fauria was undergoing tests including an MRI and he’s uncertain if he’ll be able to play on Sunday. If he can’t go, rookie Eric Ebron will take on more responsibilities.

— Safety James Ihedigbo had a full practice on Wednesday and didn’t suffer a setback. All indications are that he will play in his first game of the season on Sunday.

— Caldwell confirmed what the media expected when he said he’s never been on Twitter and Facebook and never will.
