Yahoo! Sports uncovered documents which show that, in addition to a lengthy friendship, NFL player agent Gary Wichard and former University of North Carolina assistant defensive line coach John Blake had a long-standing working and financial relationship, as well.

Yahoo's report also discovered that Wichard's agency, Pro Tect Management, may have paid for UNC defensive lineman Marvin Austin's hotel bills during off-season workouts at ProActive Sports, a facility located a half-mile from Pro Tect's offices in Westlake Village, California.

Seattle Seahawks defensive lineman Kentwan Balmer, a former teammate of Austin's at UNC and client of Wichard's, is said to have paid for the room during one of Austin's stays, but his name does not appear on the hotel room receipts. Instead, that receipt lists Pro Tect Management, as well as the name and Marriott Rewards points of Fadde Mikhail, an NFL marketing agent who works with several Wichard clients, including Buffalo Bills running back C.J. Spiller.

Blake resigned earlier this month from the University of North Carolina, which has suspended Austin indefinitely.

Jason Cole of Yahoo! Sports reports that Wichard faces suspension by the NFLPA's Committee on Agent Regulations and Discipline. That committee is expected to meet to discuss the Wichard case, as well as cases against other agents who have run afoul of union rules, in the near future.
