Sunday notes: Bengals without Sanu

Here are some notes heading into Sunday's games:

RAVENS: Ravens defensive lineman Art Jones was devastated by the news of Chiefs linebacker Jovan Belcher, who fatally shot his girlfriend Saturday and then committed suicide at Arrowhead Stadium. Jones was a childhood friend and former wrestling teammate of Belcher. "We would all share stories how we all would make it one day," Jones wrote in a text to The Baltimore Sun, "and dream about our first nice car and house we would all own one day, things we would buy our family. He was a super hard worker that never back down from the challenge. ... I'm thankful for all the great times that we shared together and all the great memories he is giving me. He definitely will be missed by me and all the lives that he has impacted."

STEELERS: The Ravens can win their fourth straight game over the Steelers today, something that hasn't been done by either team in this rivalry in 10 seasons. “They’ve beat us three times in a row. They kind of have our number right now,” safety Ryan Clark told the Pittsburgh Tribune-Review. “But it’s like the same old Steelers going to play the Ravens, playing as hard as we can, and we’re going to try win a football game.”

BENGALS: Wide receiver Mohamed Sanu is likely done for the season, according to the team's official website. Sanu, who had established himself as the No. 2 receiver opposite A.J. Green, is expected to go on injured reserve Monday after having surgery. He suffered a stress fracture in his left foot during Thursday's practice. Andrew Hawkins is scheduled to return today after missing the past two games with a knee injury.

BROWNS: Cleveland's run defense may be turning the corner. The Browns are coming off back-to-back games in which they surrendered fewer than 65 yards rushing for the first time since 1989, according to The Plain Dealer. "Guys are taking ownership of the defense," middle linebacker D'Qwell Jackson said. "Once you taste success it's like a drug, and you want to do anything you can to get it again." The Browns are playing at Oakland, which has the 29th-ranked run offense.
