What can give us Hope is the Tough Blonde Bull Rams RB Les Josephson in 1968 tore his Achilles tendon and missed the entire season but came back the next yr. That was a long time ago. In a interview they asked him what is the most important thing a NFL Player needs and he said a good Dr lol !
At the time of his interview he had 19 stitches across the bridge of his nose. In 1969 he suffered a broken jaw but continued to play. He passed on in 2020, he sadly had been showing signs of CTE.
But he had been signed by the Cowboys as a UDFA in 1964 got traded to the Rams and retired in 1975. Rest in Peace Les. GO RAMS !
