One of the NFL's arguments for why Jimmy Graham shouldn't receive the franchise tender as a wide receiver is the fact he lists himself as a tight end on his Twitter bio, according to a report.

Graham's grievance hearing began Tuesday and is expected to conclude Wednesday. At stake is whether the New Orleans Saints will be required to offer Graham a one-year franchise-tag salary of $7.035 million or $12.3 million.

Arbitrator Stephen Burbank will hear arguments from the NFL Players Association and the NFL Management Council to determine if Graham should be officially labeled as a tight end or a wide receiver for franchise-tag purposes. It's unclear how long it will take Burbank to issue a ruling, though one week is a fair guess based on past arbitration hearings.

Even more critical is how the ruling will affect their negotiations over a long-term contract. The two sides have until July 15 to reach a long-term agreement, or else Graham can only play under a one-year deal this season.
