O'Malley was cut by the Raiders on Saturday, but was given a spot on the 10-man practice squad, ESPN's Adam Caplan reports.
The Raiders elected to proceed with three options at tight end in Lee Smith, Clive Walford, and Mychal Rivera when it came time to cut the roster down to 53. O'Malley will have a chance to be called up at some point throughout the regular season if he impresses on the practice team.
