Mayer caught two of three targets for three yards in Sunday's 22-10 loss to the Chargers.
Mayer averaged just one yard per target in the Raiders' season opener, while rookie tight end Brock Bowers paced the team in receptions with six grabs for 58 yards on eight looks from quarterback Gardner Minshew. Despite being the No. 2 TE option in Las Vegas, Mayer played only seven fewer snaps than Bowers' 41, but the former's fantasy output could remain touchdown dependent, whereas Bowers seems better positioned to see more consistent target volume.
