The Gunners star was stepping up his comeback from a broken leg with another outing for the under-23s against Manchester City on Monday night.
However, Wilshere was sent for an early bath after reacting angrily to a challenge from City’s Tyreke Wilson, who also received his marching orders.
Despite the setback, Wilshere insists he’s got the fire back in his belly.
He wrote on Instagram: “Well, that was eventful. Felt good to be back on the pitch at the Emirates even though it ended earlier than I thought.
“My passion and my hunger is back, buzzing for more games.”
Wilshere reacted to a challenge in the 63rd minute before furious City players ran in, with the England international and Wilson both swinging arms.
The red card was quickly brandished by the referee, to which Wilshere did not argue.
Wilshere had appeared to be targeted by City throughout the evening, with a series of tough tackles.
The incident will likely anger Arsenal bosses, who will see Wilshere’s physicality as unnecessary given that they were 4-1 up at the time of the sending off.
Reiss Nelson and Eddie Nketiah both scored braces for the Gunners.
City scored twice within 10 minutes of the red card, but Arsenal held on for a 4-3 victory.
