JACKSONVILLE, Fla. -- Buffalo Bills receiver Stevie Johnson's mother died unexpectedly Saturday at her Northern California home, The Buffalo News has learned.

A search of public records shows Rhonda Lewis was 48.

A family associate who didn't want to be identified told The News that Johnson was "devastated" to learn his mother had died the day the Bills traveled to Jacksonville but was determined to play this afternoon against the Jaguars at EverBank Field.

Johnson's mother married Bay Area neighborhood activist and hip-hop figure Andre "Herm" Lewis after Stevie was born. They met when Johnson was 2.

From a feature story last year on Johnson's upbringing as he returned to his hometown of San Francisco:

Johnson and his stepfather quickly affirm Johnson's flamboyance comes from his mother. Johnson expresses his connection -- how else? -- with a tattoo that takes up his entire right forearm. Flames rise from his wrist, where "Rhonda" is written in script, up to his elbow. A bird takes flight amid the fire. Above, it says "Live to stay fly." Underneath, "Why not?"
