TERRE HAUTE, Ind. (Aug. 16, 2006) -- Indianapolis Colts safety Jahmile Addae became ill during practice Aug. 16 and was taken to a hospital, where he was expected to undergo further tests.

Addae, an undrafted rookie from West Virginia, gave the Colts a scare when he became lightheaded. By the afternoon, coach Tony Dungy said Addae was feeling better and his vital signs had returned to normal.

But the Colts were still trying to figure out what happened.

"We're not sure what it was," Dungy said. "We don't think it was a blow to the head, and it doesn't appear of the cardiac nature, either."

Heat was not believed to be a factor, Dungy said. The morning temperature was 76 degrees and the humidity level was 52 percent -- far lower than the triple-digit heat index during the first three days of camp at Rose-Hulman Institute of Technology.

Dungy said Addae felt ill during the team's individual drills and was taken to a Terre Haute hospital for observation. He returned to Rose-Hulman in the afternoon, but was held out of the team's second workout.

Addae signed with the Colts last week after a rash of injuries depleted the team's secondary.

The Colts also worked without their kicking duo. Adam Vinatieri, signed from New England during the offseason, sat out Aug. 15 and 16 after spraining his left ankle Aug. 14.

Now the Colts could also be without their punter, Hunter Smith.

Smith strained his groin Aug. 15 and missed both practice sessions Aug. 16. He's not expected to play Aug. 20 against Seattle.

Neither injury is considered serious, though.

"My sense is that it's not going to be long-term," Dungy said. "But he won't punt this weekend."

With Smith the only punter on the roster and Vinatieri the only kicker, Dungy is improvising.

He joked that he planned to hold open tryouts among Colts players to find out if anyone could handle the punting job.

"We're going to see if we've got a couple of volunteers. Some of our quarterbacks said they punted in high school, so we're going to have an open tryout ... and decide if we need to sign another punter," Dungy said.

Another possibility is tight end Ben Utecht, who punted at the University of Minnesota.

As for the placekicking situation, Dungy said the Colts might re-sign Shane Andrus this week. Andrus signed as a free agent last spring, but was waived on the same day Vinatieri was hurt.

With Vinatieri out and Andrus not yet signed, backup quarterback Shaun King kicked Aug. 16.
