Should Cardinals fans worry about Harrison?
While it appears to be a simple knee soreness, it’s hard to ignore the amount of injuries piling up for the roster this offseason. Sean-Murphy Bunting and Starling Thomas V is out for next season, while other defensive players like J.J. Russell and Jaden Davis also sustaining injuries during training camp.
The 22-year-old didn’t miss a game last year. Harrison has built off that feat by doing a stellar job of sculpting his body for next season, via adding an considerable amount of muscle. A reason for the knee soreness is the legs not used to carry and moving at top speed with that amount of mass, but one can only suspect the cause of the knee soreness.

Arizona will need Harrison to stay healthy for the offense next season, as he remains the only viable wide receivers for quarterback Kyler Murray. Michael Wilson hasn’t illustrated he has the chops to step into the wide receiver one role and others on the depth chart are unproven.
Regardless, Harrison has been sensational in training camp, making exceptional catches over opposing defensive backs. He is showing clear signs of his develop heading into his second year. If the knee soreness and other various injuries don’t hold him back, Harrison is on a historic Year 2 trajectory.
