Huddersfield Town failed to finish their chances against 10-man Stoke City, who held on for a point at the John Smith's Stadium.
Right-back Pipa put the Terriers in front after his early strike from the edge of the 18-yard box deflected in off the thigh of Potters skipper John Mikel Obi.
Michael O'Neill's side were then gifted an equaliser midway through the first half when Naby Sarr's lunging challenge brought down Tom Clarke in the penalty area and Steven Fletcher converted the spot-kick.
But any chance of a first league win in 2021 for the Potters was dented when Rhys Norrington-Davies was shown a straight red for a challenge on Juninho Bacuna on the stroke of half-time.
