Haren faces Tyler Skaggs, a 23-year-old lefty.

Update: Much more important than this game, news came this afternoon that Kershaw has been placed on the 15-day Disabled List effective March 23.

the Dodgers are making no promises about when he will pitch again. Mainly, because there is little urgency in the season’s first few weeks given the spate of off-days, and because they want to remain ultra-conservative and make sure Kershaw is right when he returns.

Tests earlier this week showed the strained upper back muscle, behind his left shoulder. Mattingly said he does not know of any more tests scheduled as of now.

“We know what it is,” he said. “We’re not concerned that he’s going to do any damage to it.”
