[Kansas City.com] For a guy with a reputation as a loudmouth, Freddie Mitchell was decidedly low-key on his first day with the Chiefs.

No outrageous proclamations or predictions. Those presumably will come in time.

But on Saturday, after agreeing to terms on a one-year contract, he just made the customary promise about working hard to win one of the Chiefs’ wide-receiving jobs.

Mitchell fills the spot vacated by Az-Zahir Hakim when he walked out on the Chiefs last week. Technically, Mitchell can still do the same because the Chiefs indicated they won’t turn over the paperwork to the NFL until Monday.

Mitchell left no doubt he wouldn’t do that.

“I’m happy to be here,” Mitchell said after watching the Chiefs’ practice at Arrowhead Stadium. “Unfortunately, Az Hakim couldn’t come for whatever reason. I’m going to make the best out of what happened.”

“I’ve got a lot of learning to do. I’ve got to learn the playbook. So the (other) guys have an edge. There’s a lot of good competition. We’ve got a lot of good young guys out here that are fighting for starting jobs, too. It’s not given to me. I’ll have to earn it. This is the NFL. Every year there’s a young guy trying to take your spot.”
