As another day passes without J.D. Martinez's contract being finalized, it isn't unusual for free-agent deals to be held up for days or even weeks by lengthy medical reviews and/or changes in contract language based on concerns over a potential future injury. The Red Sox went through such situations with J.D. Drew (also a Scott Boras client) and John Lackey. In 2013, the Sox completely re-worked a deal with Mike Napoli after the physical revealed a hip condition.
