The Facts: 2Coach Mike Mularkey said starter Mark Campbell and No. 1 backup Tim Euhus are recovering from reconstructive knee surgery so well that both could be ready for the start of training camp in July. While the Bills worked out on one end of the field, Campbell and Euhus ran routes and went through drills under a team trainer's supervision Thursday during organized team activities. "They're right where we anticipated them, I think maybe a little ahead," Mularkey said.

Diehards Line:Campbell and Euhus suffered torn anterior cruciate knee ligaments late last season. They are into the sixth month of their recovery periods. Meanwhile, rookie tight end Kevin Everett has begun rehab on the surgically repaired left knee that he hurt during a three-day minicamp that ended May 1. Mularkey has set no timetable on Everett's return.
