MEMORANDUM AND ORDER
David J. Waxse, United States Magistrate Judge
In this civil rights action under 42 U.S.C. § 1983, Plaintiff alleges that Defendant used excessive force while arresting him on a misdemeanor traffic warrant. This matter is before the Court on Plaintiff’s Motion for Leave to File First Amended Complaint (ECF No. 9). Plaintiff requests leave to amend his complaint under Fed.R.Civ.P. 15(a) to assert state law claims for excessive-force negligence, and negligent infliction of emotional distress, as well as add allegations supporting these claims. Plaintiff also seeks to add the City of Wichita as a named defendant in the case. Defendant does not oppose the inclusion of Plaintiff’s proposed state law claim for negligent infliction of emotional distress, but does oppose Plaintiff’s proposed claim for excessive force under a negligence theory. He argues that this proposed claim is futile because the alleged acts do not describe acts or omissions properly characterized as negligence, but rather are properly characterized as intentional torts, and thus barred by the one-year statute of limitations applicable to actions for assault and battery. As explained below, the Court finds that Defendant has failed to meet his burden to establish that it would be futile to allow Plaintiff to amend his complaint to assert a state law negligence claim based on unreasonable use of force by a police officer. Plaintiff’s motion is granted.
I. Relevant Background Facts
Plaintiff alleges that on September 2, 2010, Defendant, a City of Wichita Police Department Officer, while in uniform, arrested him for a misdemeanor traffic warrant. Plaintiff is five feet six inches tall and weighs approximately 150 pounds. Defendant is approximately six feet tall and weighs approximately 225 pounds. Plaintiff alleges that during the course of the arrest, Defendant stomped on the outside of his lower left leg, breaking both his tibia and fibula and leaving it at an unnatural 90 degree angle from the rest of his leg.
Plaintiff filed his complaint in the Sedgwick County District Court on August 31, 2012, asserting a claim under 42 U.S.C. § 1983 against Defendant for excessive force in contravention of Plaintiff’s rights under the Fourth and Fourteenth Amendments of the United States Constitution. Defendant removed the action to federal court on November 16, 2012.
II. Standard for Allowing Amendment of Pleadings
Federal Rule of Civil Procedure 15(a) governs the amendment of pleadings before trial. It provides that the parties may amend a pleading “once as a matter of course” before trial if they do so within (A) 21 days after serving the pleading, or (B) “if the pleading is one to which a responsive pleading is required, ” 21 days after service of a responsive pleading or a motion under Fed.R.Civ.P. 12(b), (e), or (f), whichever is earlier. Other amendments are allowed “only with the opposing party’s written consent or the court’s leave.” Rule 15(a)(2) also instructs that the court “should freely give leave when justice so requires.” The court’s decision to grant leave to amend a complaint, after the permissive period, is within the trial court’s discretion and will not be disturbed absent an abuse of that discretion. The court may deny leave to amend upon a showing of “undue delay, bad faith or dilatory motive on the part of the movant, repeated failure to cure deficiencies by amendments previously allowed, undue prejudice to the opposing party by virtue of allowance of the amendment, futility of amendment, etc.”
Defendant, as the party asserting futility of amendment, has the burden to establish futility of Plaintiff’s proposed amendment. A proposed amendment is futile if the proposed or amended claim would be subject to dismissal. In determining whether a proposed amendment should be denied as futile, the court must analyze a proposed amendment as if it were before the court on a motion to dismiss pursuant to Fed.R.Civ.P. 12(b)(6). In doing so, the court must accept as true all well-pleaded factual allegations and view them in the light most favorable to the pleading party.Courts in this District have considered whether the statute of limitations bars the proposed claim in determining whether the proposed amendment is futile.
III. Plaintiff’s Proposed State Law Claim for “Negligence–Use of Force”
Defendant objects to Plaintiff’s proposed amendment to add a state law claim for excessive force based upon a negligence theory. He argues that it would be futile to allow Plaintiff to amend his complaint to add this claim because the alleged acts do not describe acts or omissions properly characterized as negligence, but rather are properly characterized as intentional torts. Plaintiff’s proposed claim would thus be barred by the one-year statute of limitations applicable to actions for intentional torts such as assault and battery set forth in K.S.A. 60-514(b). Defendant argues that for purposes of determining which statute of limitations applies, the nature of a state law claim should be determined by the substance of the facts alleged. Defendant asserts that Plaintiff’s allegations do not describe acts or omissions properly characterized as negligence and cites to the Kansas Supreme Court’s opinion, Baska v. Scherzer and an unpublished Kansas Court of Appeals decision, Cooper v. Hester.
Plaintiff argues that he is properly asserting a state law excessive force claim based on negligence; thus, the Kansas two-year statute of limitations for negligence actions applies and the amendment is not futile. Plaintiff further argues that the federal district court, in Clark v. Thomas, recognized an excessive force–negligence claim, citing to the Kansas Supreme Court opinion, Dauffenbach v. City of Wichita,  for the standard for this type of claim. Plaintiff argues that Defendant’s use of unreasonable force is tantamount to negligence and subjects Defendant to liability under Kansas state law. Plaintiff further argues that, though police officers may be immune from liability on claims arising from performance of their general duties, liability may arise where an affirmative act of the officer causes injury. Plaintiff also argues that Defendant has improperly raised a statute of limitations affirmative defense in opposing the motion for leave to amend the complaint, and it is improper for the Court to consider this affirmative defense in ruling on his motion to amend.
In evaluating whether the proposed amendment is futile, the Court must accept all Plaintiff’s well pleaded allegations in his amended pleading as true. Plaintiff makes the following allegations in his proposed First Amended Complaint:
The defendant officer possessed a duty to [Plaintiff] not to use excessive or unreasonable force against him.
While in the course of his employment as a Wichita Police Department Officer, the defendant officer breached his duty to [Plaintiff] and used excessive or ...
