Clemson athletic spokesman Jeff Kallin said the school learned of the NCAA’s decision on Wednesday.
All three players have denied knowingly taking the banned substance ostarine.
Lawrence was a junior who left early for the NFL and was drafted by the New York Giants with the 17th overall pick. He would have faced a suspension of the entire season.
Clemson issued a statement that it was disappointed in the ruling and continues “to believe our student-athletes did not knowingly ingest any banned substances.”
