Amano's drawn a lot of ire from Titans fans for his play, some of it deserved. The Titans looked at several veteran centers in the offseason and didn't sign any. Munchak indicated in his pre-training camp press conference Amano's lock on the center at the position wasn't set in stone, but he was apparently working with the first-team offensive line and seemed poised to start at center again. He's not a great player, but going out for the year is definitely a loss for the Titans.
With Kevin Matthews suffering from a concussion and sitting out, Fernando Velasco will be taking the first-team reps at center. The Titans also announced today they signed free agent Chris Morris, who previously played with the Raiders and Panthers but did not play in 2011.
We'll take a detailed look at how Amano's injury affects the roster when we get to the center position in our positional analysis series. For now, suffice to say there seems to be a spot on the 53-man roster that likely wasn't available a few days ago.
