It's still too soon to know who will line up in the Indianapolis Colts' secondary on Sunday at the Tennessee Titans.
Head coach Chuck Pagano said Pro Bowl cornerback Vontae Davis was limited in Wednesday practice as he undergoes the NFL's mandatory protocol. Davis was hurt in the second quarter of Monday's 20-7 home loss to the New York Jets.
Cornerback Darius Butler, who started the opener but missed Monday with a hip injury, is considered "day-to-day," Pagano said. Starting cornerback Greg Toler, who has yet to make his season debut due to a neck injury, returned to practice on a limited basis.
Rookie cornerback D'Joun Smith was placed on injured reserve with a designation to return due to a knee injury that required surgery. Smith was drafted in the third round in May. The loss of Davis against the Jets meant the Colts were without their top four cornerbacks.
The Colts signed cornerback Josh Thomas Tuesday and released cornerback Eric Patterson, who was re-signed Wednesday to the practice squad.
Also on the injury list was tight end Dwayne Allen, who didn't play the second half Monday due to an ankle injury. He didn't practice and is also "day-to-day." Allen spoke in the locker room and said he's doing everything he can to rehabilitate the ankle in time for Sunday, as the Colts (0-2) try to extend a 13-game AFC South Divisional winning streak against the Titans (1-1).
Allen has missed 18 games the past two seasons due to hip and ankle injuries.
Outside linebacker Robert Mathis was limited as part of the team's normal routine for limiting his practice time. Mathis played for the first time in more than a year on Monday due to an Achilles tendon tear. He was used as a situational pass rusher and had one tackle and one quarterback hurry in about a dozen snaps.
Second-year outside linebacker Jonathan Newsome, who missed the last game with a hamstring injury, was a full-practice participant.
Wide receiver Andre Johnson was given a day of rest.
