Holler signed a contract with the Cowboys on Thursday, Nick Harris of the team's official site reports.
Holler spent six collegiate seasons at UCF and finished with 22 catches for 225 yards and two touchdowns across 13 games in 2023. The 6-foot-3 tight end will be one of 12 undrafted free agents brought in by Dallas ahead of the team's rookie minicamp this coming Friday and Saturday. Holler will likely compete this offseason with fellow undrafted free agent Brevyn Spann-Ford and Princeton Fant for a role as a backup blocking tight end.
