Ange Postecoglou admitted Richarlison’s injury “didn’t look too good” after the Tottenham forward limped off against Liverpool.
This was only the sixth start Richarlison had made in all competitions this season, having suffered a string of injury problems in a frustrating campaign.
That continued at Anfield, as Spurs were beaten 4-0 by Liverpool in a miserable Carabao Cup semi-final defeat.
Richarlison stayed down after sprinting for the ball late in the first-half, pounding the turf in frustration as he was forced off and replaced by debutant Mathys Tel.
Asked after the match for an update on Richarlison, Postecoglou said: "It looks like his calf. It didn't look too good after the game, so probably one to add to the list."
Tel largely struggled to have an impact against Virgil van Dijk and Ibrahima Konate, on a frustrating evening for the teenager just a few days after he completed his loan move from Bayern Munich.
With the likes of Timo Werner, Brennan Johnson and Dominic Solanke currently out, Postecoglou opted to shift Djed Spence into a right wing role in the second-half, but Spurs offered little in attack.
They failed to register a single shot on target, in what turned into a tame end to their hopes of Carabao Cup silverware.
Cody Gakpo scored in the first-half to wipe out Tottenham’s first-leg advantage, before Mohamed Salah, Dominik Szoboszlai and Virgil van Dijk struck after the break as Liverpool cruised to a Wembley date with Newcastle next month.
