Guyton has been outplayed by Josh Palmer and Tyron Johnson (foot) through the first week of training camp, Daniel Popper of The Athletic reports.
The three are competing to be the Chargers' No. 3 receiver, a role Guyton handled for most of last season, though he drew only 55 targets on 920 offensive snaps. While the team could get its third wideout more involved now that TE Hunter Henry is gone, the role still figures to entail a lot of blocking and clear-out routes. The blocking responsibilities might work in Guyton's favor, but Johnson is probably the better deep threat and Palmer is the only one the Chargers really have an investment in as a rookie third-round pick.
