UPDATE: Michael Campanaro was placed on injured reserve Saturday after an MRI revealed he had a herniated disc in his back. It was not considered season-ending, but the depth at that position led the Ravens to put him on IR and free up a roster spot.
Campanaro is dealing with back spasms after making a big impact in Thursday's 23-20 overtime win at the Pittsburgh Steelers. There was concern after the game because he needed a wheelchair to get to the team bus.
His status for the Oct. 11 game against the Cleveland Browns is day-to-day, but the extra days off should help him.
Campanaro produced the first touchdown Thursday night, taking an end around and scoring on a 9-yard run. He became the second Ravens wide receiver to score a touchdown on a run and the first since Mark Clayton in 2008.
Offensive coordinator Marc Trestman said earlier in the week that Campanaro had earned more playing time. He caught two passes for 16 yards in addition to a 14-yard punt return and a 24-yard kickoff return.
