The first-round pick injured his hamstring midway through the first of Friday's two minicamp practices. Morgan sat out the afternoon session. Larry Centers, the NFL's career leader in receptions by a running back, was at Buffalo's mandatory minicamp, watching from the sidelines in street clothes. Centers, cut last week by the Redskins, has not worked out for the Bills and the team hasn't made him an offer, Buffalo president and general manager Tom Donahoe said. Centers, a two-time Pro Bowl starter, was expected to return to his home in Phoenix on Saturday.
Buffalo has one opening on roster.
Last season, Buffalo rarely used a fullback in its offense. He caught 80 passes for 600 yards and three touchdowns last season. Witnesses said Claiborne walked a woman to her car and went to his own car when a man approached him and, after an exchange of words, shot him. Brown, a starter on the Packers' Super Bowl team in 1996, is expected to be a reserve. McGrew has been a bust so far, missing 22 games due to injury and making only three tackles in two years.
