The long-anticipated debut of Jared Allen with the Chicago Bears might be pushed back a week.
The grand unveiling of the rebuilt defense figures to come at a later date, too.
Chicago hosts the Philadelphia Eagles on Friday in a preseason opener that still could provide a glimpse even if it's lacking some star power.
Allen missed practices this week with his wife giving birth to the couple's second daughter, throwing his status for this game into doubt.
If he does play, it will probably only be a cameo since starters generally make early exits.
Tight end Martellus Bennett might also miss this one after being suspended indefinitely following an altercation with cornerback Kyle Fuller in practice on Monday.
