ORCHARD PARK, N.Y. (AP) Buffalo Bills top receiver Stevie Johnson resumed practicing for the first time since hurting his back during the team's first spring minicamp session last month.

Johnson says he was limited to practicing individual drills on Tuesday, during a session closed to media not employed by the team. Calling the injury a "strain," Johnson says he felt some soreness. He says he is ahead of the initial prognosis of needing six to eight weeks to recover.

The session marked the first time Johnson has worked in a practice setting with Buffalo's new quarterbacks: veteran free-agent addition Kevin Kolb, and rookie first-round pick EJ Manuel.
