KANSAS CITY, Mo. (AP) — A.J. Jenkins never thought he’d be back in Kansas City so soon.

The former first-round pick of the San Francisco 49ers played in a preseason game against the Chiefs on Friday night at Arrowhead Stadium. On Tuesday morning, he was wearing a white shirt with that familiar arrowhead logo while participating in a walk-through before practice.

Such is the NFL, where life can be turned upside down in a matter of days.

Jenkins was traded to the Chiefs on Monday for Jon Baldwin in what amounted to a swap of wide receivers that have been disappointments. Jenkins played in three games for the 49ers last season and failed to catch a pass, while Baldwin has just 41 catches in his first two seasons.
