Sevilla midfielder Krohn-Dehli facing long lay-off

The Denmark international came on as a 59th-minute substitute in the 2-2 draw in Lviv but was stretchered off just 13 minutes later with what was later diagnosed as a fractured kneecap.

"The player has been operated on...for a displaced fracture of the left kneecap. The operation was performed without incident," Sevilla said in a statement.

The club added Krohn-Dehli, who joined Sevilla from Celta Vigo last July, would miss "between seven and eight months" depending on his recovery, meaning the 32-year-old may not return to action until 2017. 

Sevilla host Shakhtar in the return leg next Thursday as the Spaniards chase a third successive Europa League title. Unai Emery's side are also through to the Copa del Rey final against Barcelona on May 22.
