Arsenal will have to wait for a little longer to learn the extent of Alexander Lacazette's injury.
The striker was forced off during the second half of Sunday's 1-1 draw against Fulham and is now a doubt for their next clash at home against Everton.
The Frenchman has been in fine form for the Gunners, scoring two goals in each of his previous two appearances, and his absence will be a major blow for Mikel Arteta.
At Emirates on Sunday, he was replaced by Eddie Nketiah, who scored deep in stoppage time to earn the Gunners the point.
"Lacazette has done his hamstring, it's not good news," Arteta told the media.
"That's why we rotated some players because some players weren't recovered yet. But we cannot change all the players, so it's tough to see."
"We'll have to see [how long he will be out for]," he said. "We'll have the scan, probably on Tuesday, to see the extent of the injury and the timeline for it. But I don't know.
"I cannot tell if it's going to be a week, two weeks, five weeks, or six weeks. He felt something in his hamstring and we don't know the extent of it. We are all disappointed because we all know the moment that Laca was on,"
