Paul Lukas: Behind the NFL numbers. ESPN, abgerufen am 28. August 2016 (englisch): „Brian Bosworth wore No. 44 at Oklahoma and wanted to keep wearing it when he went pro. But 44 is off-limits for NFL linebackers, so when the Seahawks drafted Boz, they claimed they'd occasionally use him as a fullback. They got away with this at first, but the NFL soon put the kibosh on it, and Bosworth had to switch to No. 55.“
