Kansas City Chiefs wide receiver Rashee Rice underwent knee surgery, coach Andy Reid confirmed on Monday.Rice, 24, is facing a long recovery and rehabilitation period following posterolateral corner surgery on his injured right knee.”It’s probably the same result you get timewise as an ACL. It takes a while for that to come back,” Reid said. “He’ll get into his rehab and get rolling on that as we go here.”Rice was injured when he accidentally collided with Chiefs quarterback Patrick Mahomes in a Week 4 road win against the Los Angeles Chargers.
