Although some projected Wagner to be a late-round pick in the 2023 NFL draft, he went unselected.[7][14] Afterwards, he was signed by the Las Vegas Raiders as an undrafted free agent, being given a contract that included $225,000 guaranteed, which was the largest among their undrafted signees.[12] He was placed on injured reserve on August 29, 2023.[17]
