Buffalo Bills wide reciever Stevie Johnson could miss the majority of pre-season with a hamstring injury, according to a report.
The 27-year-old picked up the injury during Friday's training camp session as the Bills gear up for the 2013 campaign.
Johnson is now expected to miss Doug Marrone's side's games against Indianapolis Colts, Minnesota Vikings and Washington Redskins, as ProFootballTalk.com reports that he damaged his muscle.
Johnson recorded his third 1000-yard season in a row in the 2012 campaign, notching six touchdowns.
