Coach Jonathan Gannon said Thursday that Harrison will suit up for Saturday's preseason opener against the Saints, Josh Weinfuss of ESPN.com reports.
Harrison will have a chance to log some exhibition reps Saturday, though Gannon already confirmed quarterback Kyler Murray won't suit up for any preseason action. That leaves Harrison in position to catch passes from Desmond Ridder and Clayton Tune during the preseason, while he'll have to wait until Week 1's road opener against the Bills to demonstrate his chemistry with Murray. Gannon didn't offer an estimation of Harrison's expected workload for Saturday, but it would be surprising to see the rookie fourth overall pick handling too many game reps before the regular season.
