Here are some notes around the AFC North:
BROWNS: The team signed running back Thomas Clayton, who had two stints with the Browns last season, after a tryout and waived wide receiver Brian Robiskie, 2009 second-round pick. Robiskie had touchdown catches in the final three games of last season but was buried on the depth chart this year. Clayton will add depth at running back, where there have been injuries to Peyton Hillis and Montario Hardesty.
RAVENS: The team placed linebacker and special teams player Prescott Burgess on injured reserve but didn't announce any addition to the roster. Burgess, who led the Ravens in special teams tackles the past two seasons, had been cut twice and brought back both times.
STEELERS: After a team source told The Pittsburgh Post-Gazette that LaMarr Woodley is out for the Steelers' game against the Ravens, the linebacker said on a social media outlet, "Don't count me out yet. Big game on Sunday." Woodley, the AFC sack leader, injured his hamstring last Sunday. ... Head coach Mike Tomlin confirmed linebacker James Harrison (eye) has been cleared to practice. “We’ll reevaluate him a little later in the week,” Tomlin said. Harrison posted on Twitter that he would not play against the Ravens. ... Wide receiver Emmanuel Sanders, who replaced injured Hines Ward (ankle), will have his left knee evaluated. Ward is expected to return to practice this week.
