At 12:52 a.m. Tuesday, Athletic Director Dave Brandon released a statement addressing the football program's "serious lack of communication" that resulted in Shane Morris staying in Saturday's game after suffering a helmet-to-helmet hit.

The release states that Morris was diagnosed with a "probable, mild concussion." Monday, coach Brady Hoke stated, "We would never, ever, if we thought a guy had a concussion, keep him in the game."

As of Monday afternoon's press conference, Hoke did not believe Morris had suffered a head injury. The fourth-year coach said Morris "would have practiced (Sunday) if not for a high ankle sprain."

Here is the statement from Brandon in its entirety:

Statement from U-M Athletic Director Dave Brandon Regarding Student-Athlete Health and Welfare

Ultimate responsibility for the health and safety of our student-athletes resides with each team’s coach and with me, as the Director of Athletics. We are committed to continuously improving our procedures to better protect the health and welfare of our student-athletes.

I have had numerous meetings since Sunday morning to thoroughly review the situation that occurred at Saturday’s football game regarding student-athlete Shane Morris. I have met with those who were directly involved and who were responsible for managing Shane’s care and determining his medical fitness for participation.

In my judgment, there was a serious lack of communication that led to confusion on the sideline. Unfortunately, this confusion created a circumstance that was not in the best interest of one of our student-athletes. I sincerely apologize for the mistakes that were made. We have to learn from this situation, and moving forward, we will make important changes so we can fully live up to our shared goal of putting student-athlete safety first.

I have worked with Darryl Conway, my Associate Athletic Director for Student-Athlete Health and Welfare, to develop a detailed accounting of the events that occurred. Darryl is the person who oversees all athletic training personnel and serves as the liaison to the physicians we work with through the University of Michigan Health System and University Health Services.

It is important to note that our athletic trainers and physicians working with Michigan Athletics have the unchallengeable authority to remove student-athletes from the field of play. Michigan Athletics has numerous medical professionals at every football competition including certified athletic trainers and several physicians from various relevant specialties.

I, along with Darryl and our administrative and medical teams, have spent much of the last two days carefully reviewing the situation regarding Shane Morris. We now understand that, despite having the right people on the sidelines assessing our student-athletes’ well being, the systems we had in place were inadequate to handle this unique and complex situation properly.

With his permission, I can share that Shane Morris suffered an ankle injury during the third quarter of Saturday’s game. He was evaluated for that injury by an orthopedic surgeon and an athletic trainer several times during the game. With each of these evaluations it was determined that his ankle injury did not prevent him from playing.

In the fourth quarter, Shane took a significant hit and stumbled after getting up. From the field level and without the benefit of replays, medical and coaching staffs did not see the hit. Because they did not see the hit, the athletic training staff believed Shane stumbled because of his ankle injury. The team neurologist, watching from further down the field, also did not see the hit. However, the neurologist, with expertise in detecting signs of concussion, saw Shane stumble and determined he needed to head down the sideline to evaluate Shane.

Shane came off the field after the following play and was reassessed by the head athletic trainer for the ankle injury. Since the athletic trainer had not seen the hit to the chin and was not aware that a neurological evaluation was necessary, he cleared Shane for one additional play.

The neurologist and other team physicians were not aware that Shane was being asked to return to the field, and Shane left the bench when he heard his name called and went back into the game. Under these circumstances, a player should not be allowed to re-enter the game before being cleared by the team physician. This clearly identifies the need for improvements in our sideline and communication processes.

Following the game, a comprehensive concussion evaluation was completed and Shane has been evaluated twice since the game. As of Sunday, Shane was diagnosed with a probable, mild concussion, and a high ankle sprain. That probable concussion diagnosis was not at all clear on the field on Saturday or in the examination that was conducted post-game. Unfortunately, there was inadequate communication between our physicians and medical staff and Coach Hoke was not provided the updated diagnosis before making a public statement on Monday. This is another mistake that cannot occur again.

Going forward, we have identified two changes in our procedures that we will implement immediately:

We will have an athletic medicine professional in the press box or video booth to ensure that someone will have a bird’s eye view of the on-field action, have television replay available and have the ability to communicate with medical personnel on the sidelines.

We are also examining how to reinforce our sideline communication processes and how decisions will be made in order to make sure that information regarding student-athlete availability to participate is communicated effectively amongst the medical team and to our coaches.

We have learned from this experience, and will continue to improve ways to keep our student-athletes’ health and safety our number one priority.
