Representatives from the Baltimore Ravens and Baltimore Orioles partook in a graduation parade for 14-year-old fan Mo Gaba.
According to ESPN.com's Jamison Hensley, Orioles outfielder Trey Mancini was in attendance and Ravens offensive lineman Bradley Bozeman handed Gaba a game ball.
Hensley noted that Gaba, who is in the midst of his fourth cancer diagnosis, has been in hospitals for 75 percent of his life and went blind due to a tumor in his retina.
"Gaba has since had operations, aggressive chemotherapy, radiation and a bone marrow transplant to treat tumors on his neck, legs and lungs," Hensley writes.
