"We will try to persuade him not to contest, but if he does so, he would face disciplinary action by the party," Chavan said.
Deshmukh was representing Amaravati constituency as Congress candidate for the past 10 years. He won it in 2004 by over 32,000 votes.
Rajendra Shekhwat, son of Pratibha Patil, got the Congress ticket after an intense fighting with Maharashtra Minister of State for Finance Sunil Deshmukh.
Sources said that Deshmukh was replaced by the novice Rajendra as he is the president's son.
Chavan said, "There was no pressure from any quarter. Rajendra approached party as an individual and got the ticket."
