Don't worry too much about this.
"This is not something to be overly concerned about," Scherzer told reporters. "We're only a matter of days. This isn't a long-term injury."
When might Scherzer return to the hill?
"Everybody has a very good bead on what this is. We just know it’s not major. We know it’s minor. That’s where we’ve been kind of lucky to have the All-Star break to get the rest that I need. I was hoping to pitch Sunday, but the math is just not going to work out for that," he said.
"He was sore after his last start,” Martinez said. “He had an MRI during the break. It came back negative. But he’s sore, so we talked and we decided to just push him back a couple of days and see how he feels.
“We’re at a point now where he went through an unbelievable run and we’re just trying to take care of him.”
“The pause for concern is that we tried to get it going for the Kansas City start and wasn’t able to recover from the Kansas City start. Now you got to go on a little different protocol to make sure I’m 100 percent right before I step on the mound again," he said.
"We anticipated for (the back) to kind of loosen up over the All-Star break and maybe play catch Tuesday at the game," Scherzer said. "It was just still tight. Just wasn’t free enough for me to play catch. When you start doing the math on the days, I need to throw a bullpen, it just wasn’t going to happen before Sunday.”
But Scherzer is upbeat about getting back on schedule.
“Going forward, I absolutely trust everybody in the medical staff, their opinions, their diagnosis of what this is and how soon I should be ready to be back on the mound,” he said.
