Detroit Lions Pro Bowl left tackle Taylor Decker is recovering from shoulder surgery, coach Dan Campbell told reporters on Sunday.Campbell expects Decker, 31, to be on the field in early August. The Lions open the preseason against the Los Angeles Chargers in the Hall of Fame Game on July 31 in Canton, Ohio.”We feel like there’s a good chance we can get (Decker) back after the Hall of Fame Game,” Campbell said. “He’s good. Just cleaned up his shoulder a little bit and we’re going to work him back in when he’s ready to go. He’s in a good place.”The Lions placed Decker on the active/physically unable to perform list on Thursday but didn’t divulge a reason for the move.
