Rex Ryan of the Buffalo Bills had an unsanctioned meeting on Monday with La'el Collins.

Collins was not selected in last week's NFL Draft following the shooting death of his ex-girlfriend.

Police have not named Collins as a suspect or even a person of interest in the murder investigation.

Collins, who was once seen as a likely first-round selection, now is classified as an undrafted free agent and, despite his original intention to do so, cannot enter the 2016 draft, an NFL spokesman told ESPN NFL Insider Adam Schefter.
