Mike Brown was sent off early in the second half of Harlequins' victory over Wasps on Sunday.
The 35-year-old stood on the head of Wasps hooker Tommy Taylor.
With Brown due to leave Harlequins at the end of the season, and there four rounds of the Premiership left to play, it could be the end of the fullback's Quins career depending on the length of the ban which he gets for the card. Brown has signed on to play with Newcastle next seaosn.
Wayne Barnes was the official to send off Brown. It did not take long after the incident was highlighted by the television match official for Barnes to establish the necessary punishment.
"Placement is not in doubt, but it's just what's caused it. Has he been pulled onto him?" said Barnes as he watched the footage.
"It's not like he's off balance there. He's kicked out with his foot.
"It's just reckless, isn't it? It's high reckless. He's stood down and it's on someone's head.
"He's aware that there's a player around him."
