Rays' Justin O'Conner: Sidelined with back injury

O'Conner will be sidelined for the start of spring training with a back injury, Marc Topkin of the Tampa Bay Times reports.

It is unclear what caused the back injury, but it prompted the Rays to invite another catcher to big league camp, so it must be somewhat noteworthy. His timetable for return is also cloudy, as the severity of the issue is currently unknown.
