Bowers (calf) was listed as a limited participant in Wednesday's practice, Paul Gutierrez of the Raiders' official site reports.
Bowers was listed with both hamstring and calf issues on the Raiders' Week 7 injury report, but he appears to have at least put the former injury behind him heading into a Week 8 matchup with the Jets. As long as he's able to make it through the Raiders' next two practices without incident, Bowers will likely head into the weekend without an injury designation.
