Family of ex-Tennessee women's coach Pat Summitt 'preparing for the worst'

Former University of Tennessee women's basketball coach Pat Summitt is "struggling" and those close to her are "preparing for the worst," a source said Sunday morning.

Summitt announced in August 2011 that she had been diagnosed with early onset dementia, Alzheimer's type.

In a statement released on the Pat Summitt Foundation website Sunday morning:

Friends, family, former and current players have taken to social media offering prayer wishes for Summitt and her family. Among those include Tennessee quarterback Joshua Dobbs , incoming women's basketball freshman Kamera Harris, UT Football Coach Butch Jones and musical group The Oakridge Boys.

The hashtag #PrayForPat is trending.

Her all-time record was 1,098-208 (.840). She coached 47 percent of her games against ranked opponents and also had a .913 winning percentage at home (504-48). The court at Thompson Boling Arena, where the Lady Vols and Vols play, is called "The Summitt."
