Bell (knee) "mostly worked on the side" during the media-viewing portion of Thursday's practice, David Furones of the South Florida Sun Sentinel reports.
After being listed as a limited participant Wednesday, Bell appears to have taken a step back Thursday, assuming he indeed goes down as a non-participant on Thursday's practice report. Fellow rookie third-round pick Caleb Douglas (ankle) also wasn't spotted Thursday, leaving Miami banged up at wide receiver behind de facto top option Malik Washington ahead of Sunday's matchup with the Chiefs.
