The Kansas City Chiefs and San Francisco 49ers have swapped disappointing former first-round picks, the teams announced Monday.

TheKansas City Star's Adam Teicher reported on Twitter that the 49ers are sending wide receiver A.J. Jenkins to the Chiefs for wide receiver Jon Baldwin.

This season was primed to be Jenkins' breakthrough year. San Francisco took him in the first round of the 2012 draft and he didn't catch a pass as a rookie. But fellow receivers Michael Crabtree, Mario Manningham and Kyle Williams have dealt with injuries, giving Jenkins the chance to claim a major role in 2013.

He didn't take advantage of the opportunity, though. Reports last week said the 49ers were considering cutting Jenkins. Instead, he'll join former 49ers quarterback Alex Smith in Kansas City.

Baldwin was selected with the 26th pick in the 2011 draft and failed to reach expectations with the Chiefs. He caught 20 passes for 325 yards and one touchdown last season.
