Street missed five weeks during the 2012 season with a left calf strain that he sustained while he ran from the mound to first base to cover a ground ball to the right side.
Then, a year ago, Street experienced the same type of injury to the same calf, although his recovery that time was a much quicker two weeks.
"It's a factor of severity. It's inside your body, so you can't see it; you're going completely off of feel," Street said. "Last year was totally precautionary. It was in the middle of the season and I tweaked it; I could still jog on it, and it healed pretty quickly.
"But in 2012 when I did it, I could hardly walk the next day. I could put zero pressure on it. Again, it's all about the severity of the strain."
Headley's injury, on initial review, does not sound too serious. He acknowledged he was sore Sunday, using crutches as a precaution, though he could put weight on the calf. He was set to have an MRI exam on Monday.
Either way, Street had some advice for Headley.
"I would tell when it feels 100 percent, still wait a week," Street said. "The good news is it's so early in spring. He'll have time, but the calf will take a while."
