The Green Bay Packers interest in free agent Dave Tollefson is starting to heat up.

According to Rob Demovsky of the Green Bay Press-Gazette, Tollefson is scheduled to visit Green Bay on Thursday and Friday of this week.

Tollefson, a former seventh-round pick of the Packers in 2006, contributed 21 tackles and five sacks in 13 games for the New York Giants last season. Since getting signed off the Packers' practice squad before the 2007 season, Tollefson has 81 tackles, 10 sacks and three forced fumbles in 67 career games, all with the Giants.

While a defensive end with New York, the Packers likely see the 266-pounder as an option to play outside linebacker, a position that currently has no answer opposite Clay Matthews.

However, it may be a stretch to call Tollefson an immediate upgrade over what the Packers currently have, especially as a pass-rusher.

According to Pro Football Focus, Tollefson graded out as the No. 67 overall 4-3 defensive end in 2011—good for dead last on their rankings. On over 355 pass-rushing snaps, Tollefson registered just five sacks, two quarterback hits and nine pressures. In comparison, incumbent starter Erik Walden had 3/14/22 on 426 pass-rushing snaps in 2011.

Only an average pass-rusher at best, Tollefson would also have to adjust to a position change in the Packers' 3-4 defense.

Tollefson, who turns 30 in July, has had previous free-agent visits with the Oakland Raiders and Seattle Seahawks.
