Bosa’s mother confirmed to Eleven Warriors that he suffered a slightly torn ACL.
Bosa (6-4, 265 pounds) was rated the No. 6 player in the country in July by 247Sports, which rates him as the No. 1 defensive end in the country and the No. 2 recruit in Florida.
St. Thomas Aquinas AD George Smith wouldn’t discuss the nature of the knee injury, according to the Sun Sentinel, but said Bosa “will make a full recovery” and that the knee should be “good as new” after treatment.
