Midseason injury activations in jeopardy

For those who have been asking, we don't yet have any official word on the severity of injuries to a pair of Green Bay Packers defensive starters. Linebacker Desmond Bishop (knee/hamstring) and cornerback Davon House (shoulder) both departed Thursday night's preseason opener at the San Diego Chargers and are being evaluated Friday.

But I do want to pass along some important news from ESPN's John Clayton, who reported Friday that the NFL might reverse a rule change that would provide teams greater flexibility with injured players.

In May, as you might recall, NFL owners approved a new rule that allowed teams to designate one injured player to a special list that would allow him to return to the practice field in six weeks and the 53-man roster two weeks after that. Otherwise, all players who are injured must either be placed on injured reserve -- ending their season -- or carried on the 53-man roster.

The league, however, notified teams Thursday that the NFL Players Association has not yet approved that rule change, nor one that would move back the trade deadline. Without approval, the league would revert to its previous rules.

We don't yet know if Bishop or House have injuries that would make them candidates for that special midseason injury list, but now it is not clear if the Packers will have that option. There are other players in the NFC North who could capitalize on that potential option, including Detroit Lions receiver Ryan Broyles (knee) and perhaps safety Louis Delmas (knee). Stay tuned.
