Dareus sat out the Bills' last two defensive series Sunday due to an abdominal issue, The Buffalo News reports.

Dareus has had trouble staying healthy this season, possibly because he missed a month due to suspension and has been catching up with the team ever since. We'll see what his practice participation looks like later in the week, though with the Bills needing to win at least four of their last five games and possibly all of them, the team can ill afford to lose its star defensive player again.
