Free agent WR Mike Sims-Walker's Tuesday workout with the Titans was reportedly "not so good." Career special teamer Jerheme Urban looked better, according to ESPN's Chris Mortensen. Sims-Walker couldn't earn a roster spot with the receiver-needy Texans during OTAs, and the latest dismal workout suggests his career may have hit the skids for good. The 27-year-old caught 12 balls in six appearances last season.
