Everton's Steven Pienaar believes losing Yakubu for the remainder of the season is a massive blow for The Toffees.
The former Middlesbrough and Portsmouth striker suffered an injury just 11 minutes into Sunday's 1-0 win over Spurs at White Hart Lane.
Manager David Moyes revealed after the full-time whistle that Yakubu had ruptured his Achilles and that it was unlikely he would feature for the club again this season.
Pienaar, who scored the game's only goal six minutes after half-time, believes the Nigeria international's presence will be missed in the dressing room.
"It's a huge blow to lose Yak and we are all so sorry for him," he told the Liverpool Echo. "We know the quality he has got and the type of person he is.
"His presence alone in the team gives the players a boost, so it is really unfortunate for him to pick up an injury like this when we are not even halfway through the season.
"I spoke to Yak at half-time and he was really down. Maybe the win and the goal will have given him a little bit of lift. We hope he is better again quickly."
