San Diego Chargers wide receiver Stevie Johnson sustained a torn meniscus during practice on Sunday and will have surgery, reports Michael Silver of NFL Media.
Ian Rapoport of NFL.com reports that Johnson will get a second opinion on the knee and then undergo surgery. It is currently unclear how long the injury will keep him out.
Johnson signed with the Chargers before the 2015 season, recording 45 catches for 497 yards and three touchdowns last season.
The 30-year-old was competing for a starting role in a unit that is led by Keenan Allen and Travis Benjamin.
Johnson had the best stretch of his career with the Buffalo Bills from 2010–12, recording at least 1,000 receiving yards each season.
