As expected, the Titans will wear a No. 9 decal on the back of their helmets this season to honor Steve McNair. I imagine it will look something like the photoshopped picture above. They will first wear the helmets with the 9 against the Bills this Sunday in the Hall of Fame game. A jersey patch was not allowed because they are already wearing a patch for AFL's 50th year celebration. Per league rules, only one patch is allowed each year. The Titans are still working on other ways to honor McNair this season, according to The Tennessean.
Update: The decal will actually look like the picture below.
