Brian Bosworth and another former Oklahoma player tell Yahoo! Sports that former North Carolina assistant coach John Blake introduced them to agent Gary Wichard.

Blake's relationship with Wichard is part of the focus of investigations by the University of North Carolina, the NCAA, the NFL Players Association and the North Carolina Secretary of State's office.

Blake resigned from North Carolina's staff Sept. 5 and has denied steering players to Wichard.

Bosworth tells Yahoo! that Blake, an assistant at Oklahoma in the mid-1980s, introduced him to Wichard and set up all his meetings with the agent. Former Oklahoma tight end Stephen Alexander also told Yahoo! that Blake set up his meeting with Wichard.
