Updating our earlier item about Chad Billingsley‘s next start on March 28, the Dodgers haven’t determined where it will be.

It definitely won’t be in Anaheim. Manager Don Mattingly said Saturday that Hyun-Jin Ryu will start the “Freeway Series” opener against the Angels at 7 p.m.

There’s also a 6 p.m. split-squad exhibition game that night against the Single-A Rancho Cucamonga Quakes at The Epicenter. That would be the logical place for Billingsley to start, but it would cause a minor inconvenience if the Dodgers decide to put the right-hander on the 15-day disabled list with a bruised index finger when the regular season begins.

If Billingsley pitches in Rancho he wouldn’t be able to start his potential disabled list stint until March 29 because the exhibition game has a paid attendance. That’s an MLB rule. If the DL is still a possibility for him in four days, Billingsley would pitch in a game without a paid attendance, such as a simulated game at Camelback Ranch.

Billingsley wouldn’t be eligible to come off the DL until April 13 if he starts against the Quakes.

Even though he was able to pitch 4 2/3 pain-free innings Saturday, Billingsley didn’t throw a curveball because he can’t throw a curve without pain. Last year Billingsley threw curves on less than 3 percent of his pitches, but Dodgers manager Don Mattingly said that Billingsley “is going to need to have all his weapons” by the time he makes his first start of the season. Right now, that’s scheduled for April 2. If Billingsley goes on the DL, Ryu will make the start instead.

Speaking of Ryu, here are the projected Freeway Series matchups:

Thursday (in Anaheim): Ryu vs. Joe Blanton
Friday (in Los Angeles): Josh Beckett vs. Jason Vargas
Saturday (in Anaheim): Zack Greinke vs. Tommy Hanson
