David Diehl, whose future as the Giants’ right tackle is still unknown, recently underwent arthroscopic knee surgery and has been doing his rehabilitation this offseason at the Giants’ Meadowlands practice facility.
A source confirmed that the 32-year-old Diehl had the minor procedure on his right knee shortly after the Giants’ season ended. Even though the exact injury isn’t known, Diehl did sprain his right MCL early last season, causing him to miss three games.

Diehl is expected to be ready for the start of offseason workouts on April 15, according to the source. But it’s unclear if Diehl will still be with the Giants then. He is due a $4.825 million salary in 2013 and carries a salary-cap number of a little more than $6.9 million. At the NFL scouting combine last week, GM Jerry Reese declined to say if Diehl is still in the Giants’ plans or whether he’ll be asked to take a pay cut.

Cutting Diehl would clear approximately $4.9 million under the salary cap for the Giants, who are believed to be about $5 million-$6 million under the projected salary cap of about $121.1 million (though some sources expect it will be slightly higher than that). However doing that now could also leave them thin along the offensive line where left tackle Will Beatty and left guard Kevin Boothe are scheduled to become unrestricted free agents.
