A former NFL player and Dallas Cowboy has filed a lawsuit in a Dallas County court against former Dallas Maverick and All-Star Rolando Blackman, who he says convinced the cornerback to invest in a faulty African gold venture.

The former NFL player, Nathaniel Jones, met Blackman and fellow defendant David Mureeba, chief executive of a tech company, through “friends and contacts,” according to the lawsuit filed this week.

Last spring, the two defendants in the suit presented Jones with an opportunity to invest in exploration and refinement of gold through another of Mureeba’s businesses, East Africa Power & Energy. They told him his investment of $150,000 would be used to airlift precious metals from East Africa to Belgium, where the gold would be sold to a refinery, according to the lawsuit.

Mureeba and Blackman guaranteed Jones a 4 percent return on his investment. Mureeba encouraged the former football player to invest more.
