Raiders place Rock Ya-Sin on injured reserve

A day after returning to practice with limited work Wednesday, Raiders cornerback Rock Ya-Sin saw his season end. The team placed him on injured reserve. Ya-Sin injured his knee in Week 13 against the Chargers, and he had not played since. It is unclear whether Ya-Sin re-injured his knee Wednesday. Amik Robertson and Tyler Hall [more]
