BOSTON — A friend of the Boston Marathon bombing suspect is expected to plead guilty to a reduced charge of lying to the FBI.

In a court filing Tuesday, prosecutors amended the charges against Khairullozhon Matanov (hy-ROO'-luh-zhahn MAH'-tuh-nahf), a cab driver from Quincy. He had been charged with lying and with deleting information from his computer. A judge scheduled a Jan. 27 plea hearing.

Matanov's lawyer, Paul Glickman, has not said if Matanov plans to testify against bombing suspect Dzhokhar Tsarnaev (joh-HAHR' tsahr-NEYE'-ehv). Jury selection began last week in Tsaraev's trial.

Matanov is accused of lying about contact he had with Tsarnaev and his brother, Tamerlan Tsarnaev (TAM'-ehr-luhn tsahr-NEYE'-ehv), after the 2013 bombings. Three people were killed and more than 260 injured. Tamerlan died after a shootout with police days later.
