We've all heard of NFL players losing money in shady investment deals. But this is staggering.

San Francisco 49ers kicker David Akers testified in front of a federal jury on Monday about losing $3.7 million investing with Triton Financial of Austin, Texas, from 2007 to 2009.

Akers claims he got some bad advice from Kurt Barton, the former chief executive of the company.

"I've had a lot of sleepless nights," Akers told the Austin American-Statesman. "This is my family's future. I said that to Kurt a lot of times. I said, 'Man I'm trusting in you.'"

Prosecuters say Barton regularly lied to investors about where their money actually ended up; instead he built up a $50 million Ponzi scheme.

Barton says it was just a series of bad business decisions, nothing illegal.

Safety Sean Considine of the Carolina Panthers says he was also ripped off in the scheme. Considine met Barton in 2007 while playing for the Eagles. Koy Detmer -- with Philadelphia at the time -- and his brother, Ty, a Heisman Trophy winner, introduced Barton to the Akers and Considine.

Undrafted out of Louisville, Akers has played for the Redskins, Eagles and 49ers in a career that has included five Pro Bowl trips. Akers also was part of the NFL 2000s All-Decade second team. No player in the NFL scored more than Akers' 1,169 points from 2000-09.
