Martin O'Neill's £7million summer capture has defied the problem in recent weeks and continued to play with Wilfred Bouma still sidelined and Nicky Shorey on loan at Nottingham Forest.
O'Neill will want Warnock fit for the Gunners clash as Villa look to step up their bid for a Champions League spot.
He said: "Warnock has been sore for a little while. He wanted to go again (against Brighton) but he's played a lot of games for us.
"Ideally I wouldn't have minded him not playing, but at this minute Nicky Shorey is on loan at Forest and, even if he came back, would have been suspended at the weekend.
"Stephen is a great lad who would play when a lot of other players wouldn't risk it as much so we'll have a look at things.
"He will try and rest up for a day or two and see how he is for Wednesday."
O'Neill added: "Stephen doesn't remember getting hit on the shin but our doctor seems to think he probably has at one stage or another and it's really irking him."
The Villa boss will be hoping skipper Stiliyan Petrov, defender Richard Dunne and striker Emile Heskey are also available after missing the 3-2 win over the Seagulls with various injuries.
