Kahnle (forearm) is on track to return from the 60-day injured list later in September, Jack Harris of the Los Angeles Times reports.
Kahnle began his rehab assignment with Triple-A Oklahoma City on Aug. 24, so the Dodgers will have 30 days from that date to evaluate him before he'll have to be activated or pulled off the assignment. Through his first three appearances with the OKC Dodgers, Kahnle has covered three innings while striking out two and allowing two earned runs on four hits and two walks. Los Angeles manager Dave Roberts said Victor Gonzalez (elbow) and Danny Duffy (forearm) are on similar return timelines, so the Dodgers may not have room for all three arms on the 28-man active roster down the stretch even if they all avoid setbacks during their respective rehab assignments.
