Los Angeles Dodgers left-handed pitcher Clayton Kershaw was scratched from Sunday's scheduled start due to inflammation in his back, the team announced Wednesday.
The two-time Cy Young Award winner had an MRI on Wednesday that revealed the inflammation. He reported discomfort from playing catch Tuesday.
"It's nothing that I'm too worried about. It's really frustrating more than anything. The timing of it," Kershaw told ESPN. "It's just one start that has to be pushed back. It's definitely something that if I had to pitch tomorrow, I could probably do it. It just wouldn't feel great."
The team will not schedule his next start until they see Kershaw's progress while throwing during the next week. He would have faced the San Diego Padres on Sunday night.
"We're not overly concerned," Dodgers manager Don Mattingly told ESPN. "We just don't want to let it turn into something bigger. We've got lots of off days. We're at the very beginning of the season. And we want him, once he gets going, to stay in it."
Kershaw, 26, won the MLB opener over the Arizona Diamondbacks in Australia last weekend, working 6 2/3 innings and allowing five hits, one walk and one run while striking out seven. He made 102 pitches.
Kershaw was 16-9 with a 1.83 ERA and 232 strikeouts in 236 innings last season.
Kershaw is the fourth Dodgers starter with some ailment, as Josh Beckett is on the disabled list with a bruised hand, Chad Billingsley is recovering from Tommy John surgery and Hyun-Jin Ryu has a torn toenail.
