San Francisco 49ers defensive lineman Kaleb Ramsey was suspended four games without pay Tuesday for violating the NFL's policy on performance-enhancing substances, according to CSN Bay Area's Matt Maiocco. ESPN's Josina Anderson confirmed the report, citing agent Thomas Santanello as a source.
"He took an over-the-counter supplement from GNC that contained a banned substance," Santanello said, per Anderson. "It was a mistake. He is very apologetic."
John Dickinson of 95.7 The Game reported the team signed cornerback Chris Davis to its practice squad as Ramsey's replacement.
