John Harbaugh addressed Collins’ death in a statement as well.

“Alex was a joy to be around and someone whose light shined brightly,” Harbaugh said. “I’ll always remember him for being a great teammate who had an uplifting spirit that impacted everyone he encountered. He was also a smart player who ran with unlimited determination, and he contributed to a lot of our success during his time in Baltimore. We send our heartfelt condolences and support to Alex’s family. May he now rest in God’s eternal peace.”

USFL president of football operations Daryl Johnston told FOX Sports, “The USFL family is absolutely heartbroken by the passing of Alex Collins. He played the game of football with such passion and was a great teammate and ambassador of the game. Alex represented the best of our sport both on and off the field. On behalf of the USFL family, the Memphis Showboats, and our fans who watched and cheered his incredible talents, we send our deepest condolences to Alex’s family, friends and teammates.”
