The 6-foot-4, 325-pound Bridges is not expected to start for the Panthers, but could eventually work into a backup role if he shows promise.
Carolina is likely to move right tackle Jordan Gross to left tackle and bring Todd Fordham off the bench to play right tackle.
Bridges spent the past two seasons with the Arizona Cardinals before being released during training camp this season. He played in 21 games with 11 starts for Arizona during that span. However, the Cardinals have typically had one of the league's worst offensive lines.
Originally drafted from Southern Mississippi in the sixth round in 2003 by Philadelphia, Bridges was inactive for all 16 games as a rookie.
Wharton, who had started the last 20 games for the Panthers at left tackle, tore the ACL and MCL in his left knee during Carolina's 20-6 loss to the Atlanta Falcons on Sunday.
It marked the third straight season the Panthers have not only lost their home opener, but also lost a key starter to a season-ending injury on the same day.
In 2004, the Panthers lost wide receiver Steve Smith in a loss to Green Bay on Monday night. Last year, the Panthers lost defensive tackle Kris Jenkins while dropping a game to the New Orleans Saints.
"We'll evaluate him day-to-day," Fox said. "When he is deemed healthy, he will be out there. Until then, it's more of the same."
The Panthers had Tuesday off and return to practice Wednesday.
"Really just guys not believing what they see," Fox said. "A couple of errors as far as blitzes. Guys were too far upfield, not inside a couple times. We didn't execute as well.
"At times it looked great and at times it didn't look great. You've got to make it look great every time and we didn't do that."
"They're all unique," Fox said when asked for an explanation. "Every game takes on a new personality, whether it's the opener, the last one, the middle one. Lots of times it's who you are and who they are. They were better than us yesterday."
"I don't think we ran the ball much the last 20 minutes of the game because of the score," Fox said.
Fox was vague on whether Williams might see an increased role this week against Minnesota.
"We'll evaluate that as we move forward with the game plan," Fox said.
Abraham had two sacks, two forced fumbles and one deflected pass.
"He's a good pass rusher," Gross said. "We knew that this week. Everybody knows that. He hit me with a couple of good moves a few times. He did a good job and I've got to do better if I'm going to be playing him the next time."
"The way we looked out there today, some of that has to be true," Minter said. "Again, I think we have to get back to what we do — that's play football. We need to forget about what they're about us."
Fox's gamble worked out as Julius Peppers got a hand on the field goal. Still, most observers believe that decision showed a lack of faith in his defense.
"Patrick Kerney and Keith Brooking stood up and talked to the team about how we owned this series," Falcons tight end Alge Crumpler said. "It was just one year where we goofed it up."
