It looks like he was going for goal rather than trying to pick-out a team-mate.
Out of nothing, Rangers take the lead!

His ball is cut out by Chris Willock, who pops it inside to Ilias Chair.
The Morocco international lets fly from 25 yards and his shot deflects off Egan and past helpless keeper Wes Foderingham.
