Former All-Pro linebacker being sued for defamation by mother of his child

This could get ugly.

Former Chicago Bears linebacker Brian Urlacher is being sued by the mother of his child for $125 million, claiming Urlacher had "conspired with attorneys and a news reporter to paint her as a murderer," according to TMZ.

Tyna Karageorge, originally Tyna Robertson, had a child with Urlacher in 2005 before later marrying Ryan Karageorge, who died from a gunshot wound to the head in December 2016.

Karageorge claims that her husband committed suicide and that Urlacher and his attorneys have falsely accused her of murder in an attempt to gain custody of their son.

TMZ provided further details as to why she is suing the former All-Pro linebacker:

Tyna had told police she and Ryan had been arguing on the night of the fatal shooting — and at one point, he reached for a pistol in her purse and shot himself. 

In her suit, Tyna claims Urlacher — along with his lawyers and a reporter for the Chicago Tribune — concocted a diabolical plot to convince officials and the public that the shooting was NOT a suicide, but rather Tyna murdered Ryan. 

Tyna claims Urlacher called the shots in the plot hoping to ultimately get custody of their son. 

According to court documents filed in Illinois, Tyna wants $25 mil in compensatory damages and another $100 mil in punitive damages.

Urlacher refused to comment to TMZ regarding the lawsuit.

The former linebacker spent his entire career with the Bears from 2000-2012, which included eight Pro Bowls, a Defensive Rookie of the Year Award in 2000 and a Defensive Player of the Year Award in 2005.
