After weeks of trying to play through a right quadriceps injury, Yoenis Cespedes is headed for the 15-day disabled list.

“Until it heals completely, I won’t be at 100 percent,” Cespedes said Wednesday after the Mets’ 9-5 loss to the Yankees at Yankee Stadium.

When Cespedes first sustained the injury on July 8, he rested for nine days that overlapped with the All-Star break. Although the injury was only about 90 percent healed, he returned on July 17, and the Mets moved him from center field to left to limit his running.
