Overview

• Referee Deniz Aytekin showed Vieira a straight red in the 98th minute after a high challenge on Leopold Querfeld during a 0-0 draw.
• Replays indicated Vieira missed the ball and made contact with Querfeld’s shoulder and upper arm as the defender clutched his face.
• Vieira received several minutes of on-field treatment for a knee complaint before limping off without a stretcher, and club officials later downplayed fears of serious damage.
• A red card triggers a minimum one-game ban in the Bundesliga, and Hamburg coach Merlin Polzin said he expects only a short suspension after arguing Vieira pulled back and made no head contact.
• Hamburg, newly promoted and 13th with five points, next host Mainz as Vieira serves at least one match out during a loan spell from Arsenal that includes an option to buy.
