Sanchez played 71 minutes during Arsenal's FA Cup match against Middlesboro on Sunday, and manager Arsene Wenger did not mention him as an injury concern during Thursday's press conference, which implies he's fit for Saturday's match against Crystal Palace.

There was an expectation that Sanchez would sit the FA Cup match out in order to let him rest a few niggling injuries, but there he was in the starting XI and playing most of the match. With Danny Welbeck and Theo Walcott fit, Wenger has plenty of support if he wants to give Sanchez a rest here and there.

Sanchez suffered a "knock to his knee" during Tuesday's match against Leicester City, manager Arsene Wenger said.

Sanchez started the match after sitting out the North London derby on Saturday due to a hamstring ailment, but he played only 68 minutes Tuesday before having to come off. Wenger explained that he only planned on playing Sanchez for 45 minutes, but the Chilean told him at halftime that he could keep going, so he kept him in. It appears to have backfired on Wenger, who likely won't have Sanchez for Sunday's FA Cup match against Middlebrough, though he could return Feb. 21 to face Crystal Palace.

Sanchez was limited to 68 minutes in Tuesday's 2-1 victory over Leicester City, dealing with a lower-body injury from the first half. None of his four shots were on target.

It was surprising Sanchez played some of the second half, as he wasn't close to top form and he's just returning from a separate hamstring injury. That said, perhaps Sanchez's extended appearance speaks to the Gunners not being overly concerned with his first-half tumbles. We'll see how Arsene Wenger details the injury in the next few days.

Sanchez is in the starting XI for Tuesday's match against Leicester City.

Sanchez missed last Saturday's North London Derby because of the injury, but he returns against one of the worst teams in the Premier League, an excellent fantasy matchup in all formats.

Manager Arsene Wenger said Monday that Sanchez (hamstring) will be available for Tuesday's match against Leicester City.

Sanchez missed Saturday's North London Derby due to the injury, and while he apparently was pressing to play regardless of the team's medical report, Wenger decided to hold him out. From a fantasy perspective, it's an excellent match to return to and he could be a great play if he starts.

Sanchez (hamstring) is not in the 18-man squad for Arsenal's trip to White Hart Lane on Saturday.

Manager Arsene Wenger all but ruled Sanchez out Thursday, though he hedged a number of times, including saying Friday that Sanchez wanted to overrule club medics, who said shouldn't play. Danny Welbeck gets the start on the right flank, with Theo Walcott on the bench Saturday, with Sanchez now looking to return Tuesday against Leicester City.

Arsenal manager Arsene Wenger said Thursday that Sanchez (hamstring) is not fully fit, but he could return Tuesday against Leicester City. "The latest is that Alexis is not ready," Wenger said. "He is not far away, the Leicester game is a possibility. He is of course very difficult to keep quiet! He is training but it's light training."

Given the potential return date of Tuesday, Sanchez looks all but certain to not play Saturday against Spurs, with Theo Walcott likely filling in on the right attacking wing again.
