Updated: Panthers receiver Steve Smith has vowed to play on Sunday against the 49ers.  He also has vowed to practice on Wednesday. On Wednesday, he’ll deliver on the first of the promises.  Per a league source, Smith is expected to practice on a limited basis with a knee injury. 

Smith hasn't practiced in over two weeks, so a lot is riding on his participation today in regards to this weekend's game. As long as Smith can go through practice the next couple of days there is no doubt that he will suit up for Sunday's game against the Niners. ANALYST: Matthew Beck
