Arsenal winger Theo Walcott will sidelined for Wednesday's Champions League match at Montpellier with a shoulder injury, manger Arsene Wenger said Tuesday.
The 23-year-old Walcott injured his shoulder in the north London derby against Tottenham on Saturday, a 5-2 win for the Gunners.
"It's the injury he got during the game with his shoulder," Wenger said. "We have to scan that (Tuesday) and see if there is no damage. He will be out for (Wednesday) but it should be short-term."
Walcott has three goals and four assists in 10 English Premier League matches this season, and one goal in the Champions League.
Defender Andre Santos will also miss the game with an abdominal strain, Wenger said.
