After a bright start from Paul Stephenson's side, Sylla stepped up from 12 yards to dispatch from the spot after Mitch Curry was brought down. 

However Villa rescued a point when Cameron Archer, introduced at half-time, grabbed the leveller 16 minutes from full-time at the Banks's Stadium in Walsall.
