Nugent missed kicks of 49 and 48 yards Sunday and was 2 of 6 on field goal attempts through four games.
The Bucs worked out former Indianapolis kicker Shane Andrus and signed him as Nugent's replacement on Monday.
Andrus began the season with the Colts, handling kickoff duties in the team's opener against Jacksonville. He made 5 of 6 field goals and converted four extra points to lead Indianapolis with 19 points during the preseason.
The Bucs also released reserve cornerback Marcus Hamilton. His roster spot could be filled this week when safety Tanard Jackson is eligible to return from a four-game suspension for violating the NFL's substance abuse policy.
