Matt Mika's family has released an updated state and say that he will remain in intensive care through at least the weekend.

According to the statement, Mika underwent additional surgery that doctors say went well. His family says he is also communicating with them through written notes -- he's even signed the game ball used for the Congressional Baseball Game.

Mika was shot multiple times at the congressional baseball practice on Wednesday. An Oakland County native, Mika graduated from Adrian College in 2001. He also attended Western Michigan University for a graduate program.

Read the full statement from Mika's family below:

"We want to thank the team at George Washington University Hospital for their world-class care, and we continue to be grateful beyond words for the heroic actions of the U.S. Capitol Police this week. In addition, the positive thoughts, prayers and words of encouragement from across the nation have meant the world to Matt and to all of us.

Matt has undergone additional surgery and his physicians have reported positive results. Matt will remain in the ICU through at least this weekend. He continues to communicate with us through notes, and even signed the game ball for the Congressional Baseball Game. Matt especially valued the professionalism of the officers of the Capitol Police, and would appreciate contributions to the Capitol Police Memorial Fund, one of the designated charities at Thursday night’s ballgame.

While we know there will be difficult and challenging days ahead for Matt and our family, the physicians and specialists at Matt’s side expect a full recovery. This will be our final update pending Matt’s discharge from the hospital. We again ask for your understanding and respect of our family’s privacy"
