Carl Crawford's status is also a question mark.While Crawford likely will be out, Ryu has been scratched from his start for the Dodgers against the Colorado Rockies in the finale of this three-game set Sunday.Last-place Los Angeles (23-31) has a disabled list that includes most of its top players, including Matt Kemp, Hanley Ramirez, Josh Beckett and Chad Billingsley.It's unclear if Crawford will join them after suffering a left hamstring cramp while legging out his second double in two at-bats during Saturday's 7-6, 10-inning loss to Colorado (29-27). He has a .340 average in 12 meetings with the Rockies."It's kind of getting ridiculous," manager Don Mattingly said. "The last couple of days, two outfielders (Kemp went on the DL two days ago), kind of our main guys."Ryu (6-2, 2.89 ERA) is also nursing a foot injury, stemming from a comebacker off his left foot during Tuesday's 3-0 win over the Los Angeles Angels. Still, the left-hander tossed a two-hitter for his first complete game.The Dodgers, however, decided to scratch Ryu and call up Matt Magill (0-0, 5.50) from Triple-A Albuquerque to start Sunday. The right-hander, who arrived in the Los Angeles clubhouse at Coors Field about 2 1/2 hours before game time, last started for Los Angeles on May 19, yielding one run with eight strikeouts in five innings of a 5-2 loss at Atlanta.Colorado will send Jorge De La Rosa (6-3, 3.16) to the mound looking for back-to-back wins after Dexter Fowler's walkoff single scored Yorvit Torrealba on Saturday.De La Rosa has been very good lately, going 4-0 with a 2.08 ERA in his last five starts. He hasn't won five consecutive decisions since a seven-game run June 21-July 30, 2009.The left-hander could have climbed closer to that mark with a little help Tuesday at Houston after yielding one run in seven innings before leaving without a decision in a 2-1 win.De La Rosa has never beaten the Dodgers, going 0-8 with a 6.75 ERA in 14 games -- 10 starts. This will be his first start versus Los Angeles at Coors Field since Aug. 27, 2009.
