EAST LANSING, Mich. -- Michigan State's Mark Dantonio was released from the hospital Tuesday, two days after suffering a mild heart attack following a daring overtime win against Notre Dame.

Dantonio released a statement Tuesday night expressing his gratitude for the "overwhelming and comforting" support he has received as he focuses on his recovery at home with his family.

"I haven't established a timeline for my return, but I have the utmost confidence in Coach [Don] Treadwell and the rest of the coaching staff to carry on with business as usual in my absence. I know that I must gradually work my way back onto the sidelines."

Treadwell, the offensive coordinator for the 25th-ranked Spartans, was upbeat during a news conference as he described meeting with Dantonio, who was hospitalized Sunday not long after Saturday night's 34-31 victory.

"Coach was sitting up in bed in the time that I saw him, and again, just knowing him, having known him for 20 years, you usually can't fool someone when you've been with them long enough to see him in good times and bad times," Treadwell said. "I was very pleased in just looking at him and knowing who he is and seeing the strength in his eyes and just listening to him talk."
