Pierce carried six times for 14 yards with a fumble in Sunday's 23-16 loss to the Bengals. ESPN.com relays that coach John Harbaugh confirmed that Pierce was benched after he fumbled at the Ravens' 20-yard line in the second quarter of the contest, which paved the way for Justin Forsett to rack up 70 yards on 11 carries and catch fives passes for 14 yards. "We're not too enamored with fumbles," Harbaugh said. "It's not what we're looking for from our running backs." It remains to be seen how the Ravens divide their carries Thursday against the Steelers, but for now, hopes that Pierce might seize a grip on the team's starting assignment in the absence of Ray Rice, have been dashed.
