From rulebook
One Striper:
Offense
1. MAY play end but is NOT an eligible receiver and CANNOT advance the ball in a designed play but may advance the ball after the recovery of a DEFENSIVELY CAUSED fumble. The rulebook does NOT differentiate between tight end or split end, just an end in a formation.
Nothing in the rules requires a one striper lined up as an end to declare that they are indeed a 1 striper/ ineligible. So, it's suggested if you see an offense doing this, adjust your defense accordingly...
