Barnhart is out of Thursday's lineup with lower-back stiffness but, according to manager Bryan Price, should play this weekend, Mark Sheldon of MLB.com reports.
The issue doesn't appear serious, though it's worth watching as third-stringer Stuart Turner takes his place. Barnhart is likely to make the Opening Day roster if healthy and start most games while the Reds preserve Devin Mesoraco early in the season. If the latter can handle a starter's workload as the campaign wears on, however, Barnhart will lose plenty of reps. He may help fantasy owners in two-catcher mixed leagues during the spring, though.
