Did he not practice during the first day of minicamp because he missed his physical Monday?
No, according to Grigson, it's because Landry is dealing with a lower-body injury that they don't want him to "pull more."
"He's probably overusing those areas," Grigson said. "LaRon has gotten extra nicks from doing stuff on his own. He's a guy that's constantly trying to push his body to the limit. You look at him and you can see he's obviously doing something. The guy is put together better than anyone I've ever seen and explosive as anyone I've ever seen."
Landry likely won't take part in the final day of minicamp Thursday.
"The thing with LaRon is, and I know [coach] Chuck [Pagano] alluded to it he's a guy whose throttle is always full bore and he's out there in parts unknown working out and we trust him in the fact that we know he's going to go harder than anyone," Grigson said.
Landry, who has only played in all 16 games once in the past five seasons, declined to talk to the media Wednesday.
Things became cloudy when Landry wasn't on the practice field Tuesday and Pagano gave the impression he did not practice because he didn't get his physical in time.
"He was here with plenty of time, believe me, I was checking," Grigson said. "Where's 30 at? ... When Chuck and I were talking to him, he came in the other day, he looks like a picture of health. He wants nothing more to get out there more than with his brothers and show what he can do. LaRon, like last year, has a presence about him. He knows we expect great things out of him this year. We have to get him back on the field as quick as possible, but we also don't want to set him back any further."
The Colts are in a tough position because they can't monitor Landry's workouts or suggest to him to decrease his workouts because players are not required to workout at the facility outside of the mandatory three-day minicamp.
Like Pagano, Grigson thinks it would be better if Landry worked out at the facility, but he knows that's not possible unless the player chooses to go that route. Landry always spends the offseason working out away from the team.
"We can't force anyone to do anything," Grigson said. "There's always some guys who like to get away and do things on their own and we knew this when we signed him. He's always done that throughout his career. That's what we signed up for and what we expected."
