The medication he takes for his bipolar disorder could have been what caused this situation. "It was a scary moment and I'm especially grateful for the staff at the hospital and all that they've done in the last 24 hours", he wrote.
Former NFL quarterback Johnny Manziel was reportedly hospitalized Monday evening in Texas following a concert after having a negative reaction to a prescription medication. He was first there to play in a golf tournament which was hosted by his former college teammate and current Tampa Bay Buccaneers wide receiver Mike Evans.
According to Manziel, he takes lithium to deal with his bipolar disorder.
