Can I replace the glass on my iPhone seperately?

Hi there,

While running into a store earlier today, my iPhone 6 plus fell out of my back pocket and cracked, without a case. (I had been on my way to buy an otterbox for it). The LCD and touch response are working fine, but the glass is shattered and falling off.

I was wondering if its possible to replace the glass and not the LCD display? I really can't afford to drop $80 on a new glass+LCD combo, but the glass is falling apart and needs to be replaced urgently before i cut another finger on it again.
