Michigan State Spartans coach Mark Dantonio was released from the hospital Monday after being readmitted when doctors discovered a blood clot in his leg.

Dantonio was released from Sparrow Hospital in Lansing, Mich., at about noon ET, according to the school.

The 54-year-old suffered a mild heart attack Sept. 19 and underwent a surgical procedure, remaining hospitalized until Sept. 21. Dantonio returned to the office Sept. 26 and spent part of the next three days at the football complex before the blood clot was discovered Thursday during a routine post-operative exam.

A team spokesman told ESPN.com on Monday the expected time for Dantonio's return to the team is not yet known, but Michigan State athletic director Mark Hollis posted an upbeat message Monday night on Twitter.

"Coach D is feeling great," the post said. "If his doctor gives the green light, he will be at the game on Saturday."

No. 17 Michigan State (5-0, 1-0 Big Ten) plays at No. 18 Michigan (5-0, 1-0) this weekend in a matchup of unbeaten teams.

Dantonio communicated with his assistant coaches from the hospital throughout Saturday's game against Wisconsin and addressed the team through a speaker phone in the locker room after the 34-24 victory.

Dantonio's cardiologist said that blood clots "are not uncommon following a number of surgical procedures and can occur after a cardiac catheterization procedure."

Hollis said the prognosis for Dantonio is good and the coach "remains in control of our football program."

Offensive coordinator Don Treadwell continues to handle the head-coaching duties in Dantonio's absence.

Since taking over the Spartans in 2007, Dantonio has embraced the rivalry with Michigan. Michigan State beat the Wolverines the last two seasons, its first back-to-back wins in the series in more than 40 years.

The Spartans are off to their first 5-0 start since 1999, when Nick Saban was their coach.
