Javon Ringer (back) did not participate in Titans practice on Wednesday. Ringer dealt with a hip injury the final few weeks of training camp, but it was his back that held him out today. The Titans are optimistic he'll be able to return on Thursday. HC Mike Munchak indicated rookie Jamie Harper could be in line for a handful of carries if Ringer isn't able to give it a go on Sunday, but it's much more likely the Titans just give Chris Johnson an even bigger workload.
