Isaac Kolstad, the former Minnesota State University, Mankato linebacker who was critically injured in a May 11 fight, is a father again.

Kolstad’s wife, Molly, gave birth to a girl Wednesday at the Mayo Clinic Health System in Mankato, a spokesman there confirmed.

It is the same hospital where Isaac Kolstad, 24, remains hospitalized in critical condition after suffering a fractured skull and traumatic brain injury.

The Kolstads have a 3-year-old daughter.

The happy news came atop other good news this week. For the first time since being attacked, Isaac Kolstad responded to verbal commands from his neurosurgeon Tuesday, twice following directions to give a thumbs-up sign. Later that day, however, Kolstad's Caringbridge web page asked for prayers, saying there were concerns about pulmonary embolism if blood clots formed and dislodged. 

Two men have been charged in the incident that left Kolstad hospitalized: Former University of Minnesota quarterback and Mankato high school football star Philip Nelson, 20, and 21-year-old Trevor Shelley, of St. Peter, Minn. A punch from Shelley allegedly knocked Kolstad unconscious. Nelson is accused of kicking Kolstad in the head as he lay on the ground.

Mayo Clinic Health System director of public affairs, Kevin Burns, said both Kolstad's wife and baby were doing well Thursday morning.
