The Manchester City midfielder's previous deal at Bescot Stadium expired after Saturday's FA Cup tie away at Brentford.
However, following discussions, the 21-year-old will now remain with the Saddlers until after their League One clash against Fleetwood Town later this month.
Evans has scored four goals from his 15 appearances in all competitions for Walsall.
