Daemetrius Walker, 18, was once one of the top high school football players in the state of Michigan who dreamt of one day scoring a touchdown for his state’s flagship university at Michigan Stadium.

However, according to WZZM-TV, his dream was cut short as a junior, when what started out as pain in his left knee turned out to be a type of bone cancer called osteosarcoma that spelled the end of his football career. He ultimately underwent a knee replacement after it was discovered that the cancer was not responding to chemotherapy, and later was forced to have the knee amputated completely.

Walker is currently in hospice, but on Saturday, Jim Harbaugh and the Michigan Wolverines made his dream come true. Take a look at the video below as the teenager was a guest at the team’s practice at the Big House, as Harbaugh wheeled him into the end zone amidst cheers from Wolverines players:

Later, Walker tweeted that the experience was a “dream come true”.

“They really treated me like family today,” he continued.
