The All-Pro linebacker is expected to start against the Colts later this afternoon. Jim Harbaugh made it clear on Friday that he would be ready to go for Sunday. However, he could be used sparingly on the field, according to Ian Rapoport.
Corey Lemonier and Dan Skuta would receive more playing time if Smith is used in a limited role.
Smith has previously been arrested for a DUI in January 2012 and and is also dealing with potential charges in regards to a house party incident in June 2012. He was also the passenger in a vehicle accident last season in September 2012.
