Lane Johnson declares he's done taking supplements

No more supplements, Lane Johnson says. Johnson, who faces a 10-game NFL suspension after a second positive test for a banned substance, said Wednesday he’s finished taking anything that could possibly put him at risk for a career-threatening third suspension. Johnson claims the amino acid he ordered online and took was approved by the NFL but was tainted with a banned substance that didn't appear on the label, the so-called peptide found in Johnson’s sample.
