Over the last few days, Ross has begun doing some light jogging. But rather than try to rush things, the team will backdate his 15-day DL stint by 10 days, so he will only have to miss five regular season games.
The tentative plan has him beginning a rehab stint when the Minor League season begins Thursday, then have him return sometime after the team returns from a three-game trip to Milwaukee next weekend.
"We're all on the same page," Ross said. "I mean, obviously I would have loved to have opened up the season, but we all felt like the smart thing to do was take the extra few days since we can retroactive it and I don't have to miss 15 days, I can miss the minimum.
"We felt like we hadn't gotten far enough in the running to where I could just run out there on Opening Day and not risk injury. It's a tough one to swallow, but at the end of the year we'll hopefully look back and say that was the right move."
