Here are the key injury updates heading into the early games of Week Seven:

• Vikings WR Percy Harvin (shoulder) is active at Pittsburgh. He hasn't done much lately, but he's available if you need him.
• As expected, Patriots RB Sammy Morris (knee) is out. Laurence Maroney will get the start vs. the awful Bucs and is a viable option if you're looking for a RB.
• Browns WR Josh Cribbs (knee) is active vs. the Packers. He's fine to use in return-yardage leagues.
• Bucs WR Michael Clayton (hamstring) is active vs. the Patriots. He's not much of a fantasy option at this point.
