Atletico Madrid striker Diego Costa looks unlikely to make next Wednesday's Champions League quarterfinal second leg against Barcelona due to a hamstring problem picked up in the first leg.
Costa limped out of Tuesday's 1-1 draw at the Camp Nou midway through the first half, and underwent tests back in the Spanish capital on Wednesday morning.
Atletico subsequently tweeted an injury update which confirmed there was a hamstring injury, but not a tear.
"Diego Costa has a grade 1 hamstring muscle injury in the back of his right thigh [not a tear]," the tweet said.

The club has yet to give any idea of the expected recovery time for the injury, but Costa looks sure to miss Saturday's La Liga game at home to Villarreal, and is now a major doubt for the return game against Los Blaugranas.
AS had a reporter at the clinic where the tests took place, who asked the player himself if he expected to be fit in time for that game -- Costa answered: "I will not be back in time."
The Brazil-born Spain international has scored 33 goals in total this season, including seven in his first five Champions League games.
Atletico coach Diego Simeone will likely now turn to Diego Ribas, who scored a superb 30-yard effort after replacing Costa at the Camp Nou.
Raul Garcia, who was suspended for Tuesday's first leg draw, also comes back into contention as a replacement for the return game.
