Yankees manager Aaron Boone told reporters Monday that Stanton has "no timeline" to start a minor-league rehab assignment, Bryan Hoch of MLB.com reports.
Stanton has been sidelined by a right calf strain since April 24. He resumed running right before the All-Star break after receiving a PRP injection, but the veteran slugger has not progressed enough in his recovery to embark on a rehab assignment. The Yankees should have a better sense of Stanton's return timeline once he's cleared to play in minor-league games.
