Yup. 90 days active or 1 year service time, whichever comes later, to remove Rule 5 restrictions and allow you to option them. You can replace them on the 40-man roster during the season if you 60-day DL them too. Up to 30 days minor league rehab for pitchers. I think TJ surgery guys are probably good targets now -- you can stick them on the DL for as long as you need, and you probably have a ton of discretion about if/when to activate them. Had he not been protected, Melotakis would have been an ideal candidate for my optimal Rule 5 plan: April/May on the DL (60-day if you need the 40-man spot during that time), June on a minor league rehab assignment, July and August on the MLB roster if you still want the guy and you can spare the roster spot (i.e. you're not a surprise contender), and then shut them down if you want in September when rosters expand. You could pick a guy with more recent TJ surgery too, and just DL them the entire first year, and then follow this plan in the second year. I don't know if Jones will follow that exact plan, but it looks like the Brewers and other teams are incorporating elements of it for their Rule 5 picks.
