Dec. 15 (UPI) -- New York Jets coach Aaron Glenn fired defensive coordinator Steve Wilks, he announced Monday.

Defensive backs coach and passing game coordinator Chris Harris will serve as the Jets' defensive coordinator, with assistance from Glenn. Wilks spent just one season with the Jets.

"The decision was made late last night and I talked to him [Wilks] this morning," Glenn told reporters. "I felt like it was the best decision for the organization at this time. I've said this all along: I'm evaluated players, I'm evaluating coaches, I'm evaluating myself."

The Jets, who lost four of their last five games, allowed 82 points over their last two contests, including a 48-20 loss to the Jacksonville Jaguars on Sunday in Jacksonville Fla. They rank 30th in points allowed and 20th in yards allowed. The Jets have the fourth-worst run defense in the NFL.

"I thought from last week going into this week, the improvement wasn't there," Glenn said. "I thought it was time to make a change. I'm going to make the decision that's best for this organization at all times."
