SUMMARY: By the conclusion of Wednesday morning's training camp practice, three of the Titans five starting offensive lineman were out. C Kevin Mawae and G Benji Olson did not practice due to back spasms and G Zach Piller left the workout early because of a rib strain. Though X-rays didn't show significant damage, his status for Saturday night's game is in doubt. It is hopeful Mawae and Olson will be ready for the preseason opener. "We’re watching them," Fisher said. "At this point they’re not in any jeopardy of missing playing time Saturday, but they were still a little tight so we treated them aggressively this morning." Eugene Amano replaced Mawae at center, Jacob Bell shifted in to right guard and David Stewart moved into the right tackle spot. What do you think about this article? Post your comments below.
