Any help removing a stubborn tri? I've got one stubborn tri on my mesh that wont go away, and was wondering if anyone could cast a quick look at it to see if its possible to make it into a quad? 

I want to unwrap the mesh and then texture it in substance painter so I don't want any pinching. I'm still a newbie so forgive me.  I've spent probably too much time on this tri alone (haha) and whilst the Removing triangles and ngons is helpful, it doesn't help me massively.  I've tried with the knife but it ends up solving the problem but creating a new tri or ngon elsewhere.  I've tried loop cuts on either side and up and down but with same result.  

Sorry if this is a repeat question
