Grant Hanley can barely walk off the park.

Pre-match, David Gray spoke of their lightness in defence with Jordan Obita out injured and Marko Ivezic unavailable.

It's just got a whole lot lighter now.

Dundee forward Joe Westley, who was carried off early on in the game, is off to hospital with a fractured cheek bone the prognosis.

That could've been another for St Johnstone striker Josh Fowler as his shot bends just wide of Raphael Sallinger's far post.

Left-back Harry Milne is on for Hearts as the second half resumes.

Oisin McEntee is the man replaced and Jamie McCart will move into central defence.

Dundee make a change too, with Jack Moorhouse on for the injured Ryan Finnigan.

Josh Fowler should be celebrating a hat-trick!

Taylor Steven's cross is absolutely perfect, but the striker can only get the slightest of touches with his head right in front of goal and somehow sends the ball wide.
