Mayer caught three of his four targets for 16 yards in Saturday's 27-12 preseason loss to the Cowboys.
As a rookie, Mayer -- whom the Raiders took in the second round of the 2023 NFL Draft -- recorded a 27-304-2 line on 40 targets in 14 regular-season games. Following his initial campaign as a pro, it looked like the Notre Dame product would be in a position to see a significant uptick in volume in Year 2, but when the Raiders selected fellow tight end Brock Bowers 13th overall this April, that scenario became far less likely. That said, while playing alongside Bowers hampers Mayer's weekly fantasy upside, he could still merit attention in TE-friendly formats, with Paul Gutierrez of ESPN.com noting that Las Vegas' Gardner Minshew-helmed offense figures to feature a lot of multiple tight end sets.
