The Giants are about to bring back Chase Blackburn to provide depth to their injury-riddled linebacker unit, according to two people familiar with the situation.

The people requested anonymity because they're not authorized to speak for the team.

Blackburn, who played for the team from 2005-10, could sign either today or Wednesday. It's unclear who the team will cut or place on injured reserve to make room.

Blackburn made the team an undrafted free agent in 2005 out of the University of Akron. He went on to become a spot linebacker during his five seasons with the Giants. Blackburn was also a special teams captain last season.

He entered this season unsigned and worked out with the team in September. But the Giants decided to stick with four rookies.
