KANSAS CITY, Mo. -- The Kansas City Chiefs fired coach Romeo Crennel on Monday, but made no move on embattled general manager Scott Pioli despite a 2-14 season marked by blowout losses and fan rebellion.

Crennel was fired after one full season as coach, and one day after Kansas City matched the fewest wins in franchise history with an embarrassing 38-3 loss to the Denver Broncos.

"Obviously I'm very disappointed in the way our season went. At the end of the day, the NFL is a performance-based league, and we weren't able to win," Crennel said in a statement. "I want to thank the Hunt family for the opportunity as well as our players, coaches and fans for their support during my time in Kansas City. As for my future, I'm planning to take some time to reflect on this season, evaluate everything, and make a decision based on what's right for myself and my family."

The Atlanta Falcons have granted permission for the Chiefs to interview offensive coordinator Dirk Koetter for their head coach vacancy, sources told ESPN.

The interview will take place on Tuesday. Koetter is permitted to interview this week because the Falcons have a first-round bye in the playoffs. The Chiefs also asked for permission to interview Falcons special teams coach Keith Armstrong, according to a league source.

"I am embarrassed by the poor product we gave our fans this season, and I believe we have no choice but to move the franchise in a different direction," Chiefs chairman Clark Hunt said in a statement. "I will immediately begin the search for the next head coach of the Chiefs. The entire football operation will remain under review and there may be additional changes to come."

Hunt said that "no final determination has been made" about Pioli's future.
