Kirkwood suffered a hamstring injury in pregame warmups and won't play in Sunday's game against the Rams, Christopher Dabe of Sports Illustrated reports.
Kirkwood was slated for a depth role in a rematch of last season's NFC Championship, but, as evidenced by this news, won't be able to play. With the Temple product now sidelined, Deonte Harris will slide into the fourth receiver role for the contest.
