Question of the Day: What did Sebastian Johansson put in the ref’s pocket?

Bizarre footage from last Thursday’s fixture between Helsingborg and Halmstad in Sweden’s Allsvenskan.

Midway through the second half the visitors, who went on to win 3-1, decided to make a change by introducing Sebastian Johansson. And, in one of the weirdest occurrences of the year, cameras caught the number 24 slying slipping a piece of paper into the fourth official’s pocket just before running on the pitch.

Was it his phone-number? A love note?
