68 wasn't lined up in an eligible position to go out for a pass.
Doesn't matter which one reports, the only way a lineman can catch a pass is if they're lined up in the TE, WR or RB position and they report.
The reason they are reporting is because they have a jersey # that isn't eligible to lineup in the TE, FB or WR spot.
The players lined up in the C, G or OT positions are never eligible to catch a pass.
