PITTSFORD, NY — The Bills resumed training camp Tuesday; however, thunder and lightning forced the team inside with about an hour left in the afternoon session.

Tackle Eric Pears returned to practice Tuesday. Receiver David Nelson was one of five players that did not take part. Nelson was diagnosed with a strained tendon in his right leg and will likely miss between four and five days.

Up next for the Bills another night practice Wednesday evening at 6 p.m. The night session is open to the public, but a ticket is needed.
