Panthers wide receiver Steve Smith said his left knee feels ''fine'' and hopes to be ready to play Sunday against San Francisco in the NFC divisional playoffs. ''I will be all right,'' Smith said after Friday's practice. ''I should be OK.'' Panthers coach Ron Rivera listed Smith, running back Jonathan Stewart and defensive tackle Colin Cole as questionable - or 50 percent - for Sunday on the team's injury report. Smith sprained his posterior cruciate ligament in a Week 16 win over New Orleans and has not played since for the Panthers (12-4).
