Coach Tony Dungy said the team was awaiting results from an MRI exam to determine the severity of the injury. Saturday, however, will travel with the team.
"Jeff is probably for sure not going to play," Dungy said.
Defensive lineman Raheem Brock, also a starter, could be out with a hip flexor injury but is expected to make the flight.
At least five players, including two-time Pro Bowl defensive end Dwight Freeney, will not travel. Freeney has not yet practiced after having offseason shoulder surgery and is on the team's physically unable to perform list.
Others who will not be going to Japan are starting defensive tackle Josh Williams (thigh), backup defensive back Von Hutchins (foot) and two draft picks: guard Dylan Gandy (foot) and linebacker Tyjuan Hagler (sports hernia).
The Colts announced that six additional players will not be available for the game.
Defensive tackle Montae Reagor (groin), safety Mike Doss (groin) and cornerback Donald Strickland -- all potential starters -- were
ruled out. Joining them on the sidelines will be defensive backs
Brandon Lynch (foot) and Daryl Dixon (thigh) and guard Cody
Dungy expected the starting offense to be in for about 15 plays, with the starting defense expected to play slightly longer against the Falcons.
Azumah went to Denver to see an orthopedic specialist at the
request of the team.
"We let him rest it first to see if that would take care of it.
It didn't," Bears coach Lovie Smith said. "It's something that's

Miami Dolphins: Ricky Williams has been back on the Dolphins' practice field for a week, and the former Pro Bowl running back isn't concerned with trying to reclaim his old form after a year away from the game.
"I don't expect to get back to where I was a few years ago," said Williams, who returned to the NFL after walking away a week before the start of the 2004 training camp.
"As you go through life, the key is to step forward and never
to look back or get back to where you were. I am just trying to
move forward and not go backwards."
Williams will be back on the field Monday night when the Dolphins face Chicago in the Hall of Fame game. Coach Nick Saban said Williams definitely would play, but hasn't determined how much.
For his part, Williams isn't concerned with his standing on the team. Nor is he concerned with expectations.
"When you talk about expectations, it is really just your imagination telling you what you want," Williams said. "If you put your attention to the present moment and work hard today, then tomorrow will be there for you."
Dolphins coach Nick Saban said Smith hurt the elbow when he was hit in the forearm during Monday's practice. Smith is expected to be out until the early part of the regular season.
Ephraim spent the last two seasons with the Philadelphia Eagles after signing as an undrafted rookie free agent in 2003. He played in 30 games for the Eagles, with two starts.
To make room on the roster for Ephraim, the Dolphins waived linebacker Derek Curry, signed in April as an undrafted free agent.
Also Tuesday, Dolphins offensive lineman Jason Thomas underwent arthroscopic surgery on his right knee. Thomas will be evaluated on
a week-to-week basis.
Dolphins guard Eric Wilson also returned to practice after missing three days to attend to personal issues.
"It's something he's had before," Chiefs coach Dick Vermeil
said. "I'm sure he'll be out a few days."
Dunn is used primarily as a blocker and plays behind Pro Bowl tight end Tony Gonzalez.
Vermeil said wide receiver Freddie Mitchell will not undergo arthroscopic surgery on his knee as previously thought.
Vermeil said Mitchell may not return to practice for a couple of days.
