End zone: Offensive coordinator Marty Mornhinweg told quarterback Joe Flacco earlier this week that he should have showed off his stitched-up ear to trick-or-treaters on Halloween. "Have you guys seen it? Man alive," Mornhinweg said. "That would scare a bunch of the kids." … Rosburg acknowledged that he's concerned with the amount of pressure teams are getting on punter Sam Koch and kicker Justin Tucker. Tucker got a field-goal attempt blocked last week while the Jacksonville Jaguars appeared to alter a punt by Koch in Week 3. There have been several other close calls, too. "If there's anything that keeps special teams coaches awake at night, it's protection, because the first thing in being a really good special teams unit is being able to protect the punter, and being able to protect the kicker," Rosburg said. "We need to be improving that." … Tight end Delanie Walker (ankle), offensive linemen Jack Conklin (illness) and Quinton Spain (toe) and linebacker Nate Palmer (ankle) did not practice for the Titans on Thursday.
