Benfica defender Ezequiel Garay was stretchered off after suffering a nasty gash when Paul Pogba accidentally kicked him in the face following the Juventus midfielder's failed attempt at a bicycle kick.
The Argentina international was already on the deck after striving to clear his lines in the latter stages of Thursday night's Europa League semi-final second leg draw in Turin.
With the Portuguese giants defending a 2-1 first leg lead, Antonio Conte's side piled on the pressure with the game still goalless, prompting an acrobatic effort from the increasingly impressive Pogba.
However, after failing to connect with the in-swinging cross the Juventus star fell on top of the unsuspecting Garay and proceeded to boot him on the side of the head.
The 27-year-old was treated on the pitch by Benfica's medical staff before being forced to withdraw with minutes remaining.
Thankfully it had no impact on the outcome of the match as Jorge Jesus's side held on to book their place in the final against Sevilla later this month.
Andre Gomes posted an Instagram picture of his patched up team-mate after the game, showing Garay in positive spirits despite sporting significant swelling behind the large plaster on his upper lip.
