College FB Star Laremy Tunsil -- Brutal Post-Fight Pics ... In Alleged Stepdad Attack

Ole Miss football star Laremy Tunsil -- one of the best players in the country -- allegedly beat up his stepfather so badly, he gave him a black eye and a LUMP on his forehead ... and Tunsil's stepdad says he has the pics to prove it.

TMZ Sports obtained the photos ... which Tunsil's stepdad, Lindsey Miller, says were taken after he was attacked by the 6'5", 315 pound lineman at his home in Mississippi last Thursday.

Tunsil reportedly told his Ole Miss coach that he was protecting his mother after Miller shoved her during an argument ... but Miller says that's a load of crap.

Instead, Miller says he was the real victim -- claiming Tunsil exploded on him for voicing his displeasure about the college star hanging out with sports agents.
