Luis Diaz has been forced off with an injury during the first half of Liverpool's trip to Arsenal.
The Reds were level at 1-1 against Mikel Arteta's side after Darwin Nunez cancelled out Gabriel Martinelli's early opener. Diaz made a penetrating run in behind for the equaliser before firing a cross into the Uruguayan to slot home.
The Colombian stayed down after a coming together with Thomas Partey as the Gunners midfielder fell awkwardly on top of him, but carried on after a quick assessment.

But just a few minutes later he was down again, with Jurgen Klopp forced to introduce Roberto Firmino shortly before half-time.
The nature and extent of Diaz's injury is unknown, but the 25-year-old was holding his lower left leg.
