Bukayo Saka exited Selhurst Park on crutches after suffering a hamstring injury. Saka was substituted in the 25th minute and replaced by Leandro Trossard.
\"We are pretty worried about Saka\'s injury,\" Mikel Arteta said after the match.
\"He grabbed his hamstring and couldn\'t continue. He will have to be assessed but we are pretty worried, yes.\"
Saka missed two matches and an international break earlier in the season with a hamstring injury.
