Former Arkansas Razorbacks offensive lineman Brian Wallace passed away on Friday at the age of 26.

Wallace’s father, Brian Wallace Sr., told FOX 16 that his son was hospitalized in an Intensive Care Unit in St. Louis after suffering two heart attacks on Monday. The 26-year-old wasn’t able to breathe on his own and was in a coma.

Wallace experienced breathing issues during his work shift on Monday, causing him to step outside.
