Arsenal manager Arsene Wenger has confirmed that Alexis Sanchez will undergo a late fitness test ahead of Tuesday's meeting with Sunderland.
The 28-year-old scored in the Gunners' 4-1 victory at Stoke City on Saturday, but was replaced just minutes later due to a knock on his thigh.
Wenger also revealed that defender Laurent Koscielny is likely to miss out after suffering a recurrence of a calf injury, while Alex Oxlade-Chamberlain remains on the sidelines with a hamstring problem.
"We have a little bit of a problem with Koscielny but we should have everyone available," the Frenchman told Sky Sports News on Monday.
"Kieran Gibbs should be available but Alex Oxlade-Chamberlain is out. Alexis should have a test today. It didn't look good but with him he is always so eager."
Sanchez's long-term future at Arsenal currently remains uncertain, the Chile forward yet to sign a new contract.
