The condition of Arizona offensive lineman Ernest Dye was upgraded to serious from critical Tuesday after extensive surgery to repair his right arm produced a pulse.
Dye, defensive end Carl Simpson and offensive guard Lester Holmes were injured Monday when their car overturned as they were driving to a team meeting.
"Ernest's situation is day to day, then week to week," said Dr. Jerry Mohr, one of the surgeon's who operated on Dye for more than eight hours Monday.
Doctors reconnected the bone between the shoulder and elbow, then went about the precise work of repairing nerves, arteries, veins and other tissue.
After surgery, doctors could detect a pulse in Dye's arm, which means blood was flowing to the repaired limb.
"Their primary concern is to get the blood flowing and maintain it," Cardinals spokesman Greg Gladysiewski said.
It isn't known how long Dye will have to remain in the hospital.
Dye and Simpson were thrown from the car. Holmes was the only one wearing a seat belt.
Simpson was checked for pain in his hip and released. Holmes received a severe cut to the forehead and was released from the hospital on Tuesday.
Baltimore signed quarterback Stoney Case to a one-year, $400,000 contract and promised him ample opportunity to move up from No. 4 on the depth chart.
Case, 29, was cut last week by Indianapolis. He went through his first practice with the Ravens on Tuesday working behind quarterbacks Scott Mitchell, Tony Banks and Wally Richardson.
Case was a third-round pick out of New Mexico in 1995 by Arizona. He has played in four games, starting one, and has not thrown a pass in an NFL game since 1997.
Carolina began using Paul Janus as their left guard after learning that starter Matt Campbell, who went down Monday with what was described as a high left knee sprain, could miss up to six weeks.
The Panthers had been using free agent rookie Jamar Nesbit as Campbell's top backup, but they decided to take a look at Janus at the position.
Coach Jim Fassel returned to the practice field after spending time with his critically ill mother in Arizona.
Coordinators John Fox and Jim Skipper ran the team, including last Friday's exhibition victory over Minnesota, in Fassel's absence.
"The one thing that impressed me about his absence is that no one took advantage of it," defensive end Mike Strahan said. "It's always easy for guys to say: `The head coach is not here, it's like your parents are out of town, let's throw a party.' But no one did that."
Rookie Dimitrius Underwood, wavering between football and the ministry, talked by telephone Tuesday with coach Jimmy Johnson and will decide Wednesday whether to join the team, his agent said.
"He intimated to me that his priorities are football No. 2 and God No. 1," agent Craig Domann said. "He's debating as to whether he can balance them. I would suspect at some point in the future he might want to play football. I don't know whether it's going to start Wednesday."
Underwood, a defensive end and first-round draft choice, was released last week by Minnesota after he left them to pursue his faith. The rookie was claimed off waivers Monday by the Dolphins, and his conversation with Johnson was their first.
Johnson has said the Dolphins are in no hurry for the rookie to report. Even if Underwood did so immediately, he would be unlikely to play much this year after missing three weeks of training camp.
Philadelphia waived placekicker Chris Boniol and replaced him with veteran Norm Johnson. The Eagles signed Johnson, 39, to a two-year deal. Terms were not disclosed.
Johnson is entering his 18th NFL season after a four-year stint with Pittsburgh. He ranks sixth on the NFL's career scoring list with 1,657 points.
Oakland brought in free agent quarterbacks Paul Justin and Doug Nussmeier for workouts. The Raiders are seeking insurance after another sub-par performance by backup Pat Barnes and the broken leg of Scott Dreisbach.
Kicker Peter Elezovic and defensive tackle Juaquin Feazell were waived.
Elezovic, re-signed by the Bucs in January after being cut during training camp a year ago, kicked a 20-yard field goal in last Saturday's 30-3 exhibition victory over Cleveland. Feazell, signed as a free agent in April, did not play in the game.
