Taiwo Atieno's last-minute equaliser salvaged a point for 10-man Torquay as they drew at promotion rivals Oxford.
Rene Howe opened the scoring after latching onto a poor back-pass from Oxford's Harry Worley.
Adam Chapman levelled for the hosts direct from a corner and Cristian Montano headed the U's into the lead.
Torquay were reduced to 10 men when Ian Morris was sent off for a second booking before Atieno's late leveller from the edge of the box.
The draw means Torquay remain in second place but just one point above Shrewsbury and three clear of fourth-placed Crawley.
Oxford remain in the play-off places but are now only above Crewe on goal difference after the Alex beat Bristol Rovers 3-0.
VIEWS FROM THE DRESSING ROOM
Oxford United manager Chris Wilder told BBC Radio Oxford:
"I'm sure we deserve the three points but we didn't get them.
"We fell behind to a good side, a settled side. We started off really well on the front foot, and dominated the second half. We should be here talking about a 3,4 or 5-1 victory against a team second in the league but we are not.
"We took a backward step when the boy got sent off but there was a touch of nervousness about our play and we paid the ultimate price.
"It was a poor goal to concede and we should have done better with it. We should be talking about a fantastic performance against a good side but it's not to be and we've just to go again."
Torquay United manager Martin Ling told BBC Radio Devon:
"There's a tinge of disappointment that we were in a good position and threw it away.
"Being disappointed away at Oxford with 10 men probably proves how far we have come.
"The fans have been tremendous this year, they deserve all the plaudits they get.
"Automatic promotion will depend on who holds their nerve over the last four games."
