Machado has been diagnosed with a right knee ligament sprain, MLB.com's Brittany Ghiroli reports. This is excellent news considering how gruesome the injury appeared in real time, as Machado's right knee completely buckled on a swing. The O's gave an abbreviated update Tuesday, not offering a timetable regarding Machado's potential return, but it seems like there's a chance he could return this season. A more detailed update will be provided by the team Wednesday. Meanwhile Ryan Flaherty, Jonathan Schoop and Chris Davis could all see time at third base.
