49ers WR Dante Pettis suffered an apparent knee injury during Wednesday's practice and left the field early.
Pettis suffered the injury during special teams drills. He was able to walk off the field. There is now concern about the availability of Pettis for Sunday's marquee showdown against the Ravens. Pettis was officially listed as a limited participant, as were WRs Emmanuel Sanders (ribs) and Deebo Samuel (shoulder). Marquise Goodwin may get moved back up with the injuries the 49ers currently have. Keep an eye on Thursday and Friday in San Francisco.
