Minnesota has dealt with gimpy quarterback Tarvaris Jackson. Chicago is trying to get defensive tackle Tommie Harris back on the field. Green Bay has been thin at linebacker and is down a defensive end while B.J. Raji's contract negotiations drag on.
But no NFC North team is more black and blue than Detroit. The latest addition to the Lions' injury list is defensive end Jared DeVries, who suffered a season-ending Achilles injury Monday. Tom Kowalski of Mlive.com reports the Lions signed free agent lineman Shaun Smith, but as Kowalski points out, defensive line is only one of several thin positions this week in training camp.
The Lions' top four receivers all missed practice Monday. Calvin Johnson, in fact, was wearing a protective cast over his jammed thumb. And the Lions still haven't gotten No. 2 receiver Bryant Johnson on the field because of lingering issues from a golf cart accident last month. (Yes, that sentence is accurate.)
Safety Daniel Bullocks, who appeared to have a good chance to start opposite Delmas, is having knee problems again.
That's a few more key players than coach Jim Schwartz probably wants to see. But to mangle an old phrase, look at the positive: The sooner you get hurt, the more time you have to get healthy.
