The Bucs have done still more roster shuffling.

First, they have signed fourth-round pick Dre Moore, a defensive tackle from Maryland, giving them two picks under contract with more than a month remaining before training camp (seventh-rounder pick Cory Boyd is the other).

We've learned that Moore's contract is a four-year deal, one that includes an escalator in the final year of the deal.

Meanwhile, in their continued effort to eliminate players and reach the 80-man training-camp limit, the Bucs released a few more players. Among them were former USF receiver Amarri Jackson, an undrafted prospect who was signed after a strong showing in a post-draft tryout in May.

The Bucs also released receiver Charles Spiller (Alcorn State) and fullback Carl Stewart (Auburn).
