ST. JOSEPH, Mo. (AP) – Chiefs quarterback Alex Smith says that the time is approaching where he will shelve all talk about a contract extension and focus solely on football for the remainder of the season.

The Chiefs have been discussing a new deal with Smiths’ representatives for months, though the sides remain far apart. Smith said after practice Wednesday that he’s yet to set a date to break off negotiations, but he acknowledged that “at some point mentally it’ll come to me.”

Smith is due $7.5 million this season, the final year of his contract, and many expect him to get an extension similar to what Colin Kaepernick received from the San Francisco 49ers.

Kaepernick signed a six-year, $126 million deal that includes $61 million guaranteed.

Chiefs S Commings leaves field with ankle injury

ST. JOSEPH, Mo. (AP) – Oft-injured Chiefs safety Sanders Commings was carted off the practice field Wednesday after getting juked to the ground by running back Jamaal Charles and hurting his right ankle.

Commings broke his collarbone in his first practice as a rookie and was finally getting up to speed. He was trying to tackle Charles in the open field when he whiffed, turning his ankle in such a way that he was unable to put any weight on it.

Commings was in a heated competition for a backup job, and the Chiefs hoped he would push veteran Husain Abdullah for the free safety spot that opened when Kendrick Lewis departed.

Meanwhile, right tackle Donald Stephenson returned to practice after missing Monday’s workout with a left ankle injury. The Chiefs had Tuesday off.
