But just when it looked as though Bournemouth would go on and win, the prolific Wright-Phillips shot home from the edge of the area.
Bournemouth almost snatched a winner in five minutes added on for stoppages. Pugh hit the underside of the bar and Danny Ings had a shot blocked on the line by Jose Semedo at the death.
