Miami Dolphins defensive end Jeff Cross will miss the preseason and perhaps the first part of the regular season because of a back injury.
Cross, 30, who has led the team in sacks five of his eight seasons, was placed on the physically unable to perform list Saturday.
"I'm not used to being injured, so obviously I don't like this," he said. "At this point, I'll do whatever I have to get back on the field."
NOTES: Several assistant coaches from the University of Florida attended the morning practice. The team announced its home games against Dallas, Pittsburgh, Buffalo and the New York Giants are sold out.
BRONCOS: Free-agent offensive lineman Harry Galbreath, a nine-year veteran who started 16 games last season with Green Bay, signed.
GIANTS: Tackle Roman Oben, a third-round draft pick, signed a three-year deal.
JAGUARS: Andre Rison, a four-time Pro Bowl receiver, has worn No. 80 in his seven-year career. But that number belongs to former UF star Willie Jackson. "Eventually, I'm going to get it, even if Willie and I have got to tussle in the room after curfew," Rison said.
JETS: Middle linebacker and former FSU star Marvin Jones was excused from afternoon practice with what coach Rich Kotite described as a "three-day virus.'
PATRIOTS: Free-agent safety Willie Clay, who had eight interceptions last season with Detroit, signed a four-year, $6-million deal.
SEAHAWKS: Free-agent tight end Ronnie Williams, who played the past three seasons at Miami, signed a contract.
Biakabutuka talks grounded
SPARTANBURG, S.C. _ The Carolina Panthers suspended contract negotiations with first-round pick Tim Biakabutuka. "I have no desire to talk about this and given what has gone on in the NBA recently, the fans probably have no real desire to hear about this either," general manager Bill Polian said. Polian said he offered the ex-Michigan running back a four-year deal worth $7.2-million, including a $3-million signing bonus.
49ERS: RB Johnny Johnson was given a cortisone injection in hopes of relieving the back pain that has prevented him from practicing.
RAMS: WR Alexander Wright, who missed half of last season because of back surgery, missed practice complaining of a similar problem.
