Injured Ex-Football Player Undergoes Surgery Again

MANKATO, Minn. (AP) - A former Minnesota State, Mankato, linebacker who was allegedly assaulted by a former Minnesota quarterback and another man has undergone another surgery.

According to a post on his CaringBridge site, 24-year-old Isaac Kolstad remains in critical condition at a Mankato hospital.

His family says the latest surgery went as planned Friday morning. They say no further procedures or surgeries were planned for the next couple days and they're hoping for an uneventful weekend.

Prosecutors have charged 21-year-old former Minnesota quarterback Philip Nelson, of Mankato, and 21-year-old Trevor Shelley, of St. Peter, with felony assault. Shelley is accused of punching Kolstad and knocking him to the ground early last Sunday as downtown Mankato bars were closing. Nelson then allegedly kicked Kolstad in the head.

Police say Kolstad suffered severe head injuries.
