BATON ROUGE - Despite facing mounting emotional and health challenges, family of injured sheriff's deputy Nick Tullier remain positive and once again, took to Facebook Sunday morning to ask people to keep praying.

"I'm just not going to write down the prognosis we were given for Nick... He's fighting, but he has to have your prayer support," page managers wrote on a Facebook page set up to share information about his condition.  Often, his father James posts messages and prayer requests.

Sunday, Tullier was breathing without a breathing machine.  He has been breathing well, the update reported on Facebook.

"Every day is a miracle," posters wrote.  "He has only gotten here through the power of prayer.  For that, we thank you all very much.  Please keep praying."

Sunday is the twenty-first day Nick Tullier's been in the hospital.  He was shot in an ambush that killed three other officers on July 17th.
