Marcell Dareus is absent from Bills OTAs.
A reason was not provided, but it appears Dareus is simply skipping the "voluntary" workouts. The No. 3 pick of the 2011 draft graded out as the No. 11 defensive tackle in Pro Football Focus' ratings last season. He has work to do as a run stopper, but Dareus' future remains bright.

Bills OC Nathaniel Hackett admits first-round pick E.J. Manuel needs work on "everything."
Hackett's comments come two days after Manuel said the Bills' playbook was easier to pick up than Florida State's. "He's a young man that's got to work on a lot of things from footwork to progressions to plays to formations, everything," Hackett said. "Defenses in the NFL are obviously a little different. He's got to work on that too. He's got to work on everything."

Stevie Johnson (back) has been cleared to resume practicing, and participated in Tuesday's OTAs session.
Johnson said last week he had "no idea" when he'd be cleared to return, but it took less than seven days. "It was great to see him," OC Nathaniel Hackett said. "It was great to see him run some routes instead of being on the side. We've just got to work him back in." The Bills will take things slow with their No. 1 receiver before camp, but his back is not a long-term concern.
