"It [the oblique] is the second-highest rate of recurring injury, so you've got to make sure you're good to go," Hundley said.
Hundley is dealing with his second injury in 2016. He missed 10 games earlier this season with a concussion. Hundley's season illustrates the challenge of staying healthy behind the plate.
"I don't think you ever think like that; I don't, at least," Hundley said. "I take pride in doing everything I can to stay healthy. This is disappointing, but at the same time, I won't do anything different."
Rockies option Matzek, who has taken forward steps
The Rockies announced that they've activated lefty pitcher Tyler Matzek from the 15-day disabled list and optioned him to Class A Modesto. He was working through performance anxiety.
Matzek has made one-batter appearances in five games, including the previous three nights. After walking the only batter he faced in the first three games, Matzek has worked clean outings in the past two as he works toward lengthier appearances.
