Snell (groin) is expected to throw a simulated game Saturday, AJ Cassavell of MLB.com reports.
Snell went on the 10-day IL after groin tightness prevented him from making a scheduled start April 10. He threw a bullpen session April 19 and is scheduled to face batters in a simulated game Saturday. If that goes well, Snell could return to the Padres by the end of the month.
