The Giants signed Allen to the practice squad Wednesday, Michael Eisen of the team's official site reports.
EDGE Analysis
The Giants' dropped Allen as part of the team's final roster cuts Tuesday, but he returned via the team's practice squad upon clearing waivers. The 6-foot-9 rookie out of Nebraska should be an interesting developmental prospect for Big Blue, and he could even provide a receiving threat should the team suffer multiple injuries at linebacker this regular season.
