Freeman worked out for the Giants on Tuesday. He also recently visited the Chicago Bears.
Eli Manning underwent arthroscopic surgery on his left ankle Thursday but expects to be able to run again in about six weeks, the team previously announced. His 151 consecutive starts rate as the longest active streak in the NFL following the retirement of Washington's London Fletcher, and it is the third-longest by a quarterback in league history.
Freeman, 26, a first-round pick of the Buccaneers in 2009, started 56 games for the team. He enjoyed his best season in 2010, when he started 16 games and threw for 3,451 yards and 25 touchdowns with six interceptions.
He has struggled since, throwing 43 interceptions over the past four seasons.
