The Indianapolis Colts remain unsure when Andrew Luck will be healthy enough to return to the lineup.

Luck has yet to practice after suffering a lacerated kidney on Nov. 8th.

The Colts initially said Luck would be back in 2-6 weeks.

“[H]e’s been throwing,” Chuck Pagano said of Luck. “[He] hasn’t participated in practice. He’s doing his rehab and most of his stuff is with the docs and trainers and then he’ll come out and watch part of practice. I saw him doing some gassers, which was a good sign, during a couple of the periods.”
