Rice (knee) is feared to have torn his ACL in Sunday's 17-10 win over the Chargers, Adam Schefter of ESPN reports.
Rice will have an MRI on his knee Monday to confirm his injury diagnosis, but if fears of a torn ACL prove true, the injury would be season-ending. The Chiefs already have had injuries to two key skill players on offense, as fellow wide receiver Hollywood Brown (shoulder) is unlikely to play in the regular season and running back Isiah Pacheco (fibula) is in the early portion of a recovery timeline that's expected to stretch 6-to-8 weeks. Rookie first-round pick Xavier Worthy could be asked to step into a larger role in Rice's absence, with Justin Watson, JuJu Smith-Schuster, Skyy Moore and Mecole Hardman also on hand in Kansas City's wide receiver room.
