De La Rosa was bothered by his groin during Sunday's outing against the Giants, FOX Sports Arizona's Jody Jackson reports.
De La Rosa still held the Giants to just one run on a hit and four walks over 6.2 innings, with seven strikeouts on 101 pitches. His previous start was pushed back a day because of triceps tightness, but he was also effective in that outing, allowing just one run over 7.1 innings. Despite the pair of minor injuries, De La Rosa has been fantastic since he rejoined the rotation, surrendering just seven runs in five starts with a 33:10 K:BB over 32.2 innings. He's tentatively scheduled to face the Cardinals on Saturday.
