BALTIMORE -- On the field their teams may be rivals, but off the field, brothers Ma'ake and Chris Kemoeatu -- one a former Baltimore Raven, the other an ex-Pittsburgh Steeler -- are closer than close.

They share a lifelong love of football, an alma mater and now, a pair of kidneys.

Ma'ake Kemoeatu, a former nose tackle for the Ravens, donated a kidney to his brother Chris, a former offensive guard for the Steelers, at the University of Maryland Medical Center in August. The brothers are now recovering from their surgeries.

Chris Kemoeatu's football career was cut short after seven seasons with the Steelers when he learned he'd need a kidney transplant. That's when his older brother, a 99-percent kidney match, stepped in, and left the Ravens in 2012.
