Nine days after saying that Kenneth Dixon’s return from injured reserve is complicated by what Harbaugh described as “issues,” the Ravens coach had no new information on the running back, who has not played since suffering a knee injury against Buffalo. “Have had no clarity on Kenneth Dixon’s status,” Harbaugh said. … Free safety Eric Weddle is the Ravens’ nominee for the Art Rooney Sportsmanship Award, which honors one player throughout the league who exemplifies sportsmanship on the field. The winner will be announced the night before the Super Bowl. … The team announced Wednesday that it added running back Tyler Ervin to the practice squad. Ervin was a 2016 fourth-round draft pick by the Houston Texans, who employed him as their primary return specialist, including this fall, when he averaged 25.3 yards on 10 kick returns. But he sat out the past 12 games of last season because of a torn patellar tendon and was waived by Houston on Nov. 7. To make room for Ervin, the team released cornerback Makinton Dorleant.
