Mississippi State football coach Mike Leach reportedly suffered a massive heart attack on Sunday, leaving him in critical condition. EMTs used a defibrillator machine and multiple shocks to resuscitate the 61-year-old, who reportedly did not receive medical attention for up to 15 minutes after the collapse. Sources say Leach may have suffered from seizures amid the medical emergency, leaving him with possible brain damage, according to the Mississippi Clarion Ledger. Two of his four children are already at his bedside, with the other pair en route to the hospital, the newspaper reported. MSU has tapped Defensive Coordinator Zach Arnett to replace Leach as an interim coach ahead of the team’s ReliaQuest Bowl appearance on Jan. 2. “My thoughts are with my mentor, my colleague and, more importantly, my friend, Mike Leach,” University of Houston head football coach Dana Holgorsen tweeted. “While I am devastated by today’s news, I know Mike is a fighter with an incredible spirit and I know he will continue to battle.”
