Head coach Doug Pederson found out about Colts quarterback Andrew Luck's retirement Saturday night the same way most of us did – on his phone.

A 12-year NFL veteran at the quarterback position, Pederson commiserates with Luck, who cited mental fatigue from consistently rehabbing from injuries as a big reason for his decision to step away from the game.

"A lot of respect for Andrew and what he has done in his career as a quarterback. I've been in situations too where I've been hurt but obviously not to the extent he has been," Pederson said. "It's tough. It's tough. You obviously could tell through his comments last night that he put a lot of thought and a lot of conversation with family, friends, coaches, the owner, and it's a tough thing. It's a tough thing for him to be able to step away like that. I hope he gets healthy and wish him the best moving forward."

Pederson said that he talked with Colts head coach and former Eagles offensive coordinator Frank Reich after the stunning announcement, but would not divulge any of the details from the conversation.

Here's what else you need to know from Pederson's Sunday press conference:

1. Pederson said that linebacker Nigel Bradham (foot) and defensive tackle Fletcher Cox (foot) will take part in walkthroughs this week. Bradham participated in individual and 7-on-7 drills last week against the Ravens.

"I want to have everybody Week 1," Pederson said. "That's the goal and that's still the goal."

When asked a follow-up question about Cox's status, Pederson said, "I'm confident that he'll be there (Week 1)."

2. Guard Brandon Brooks has been cleared to increase his load and do more team work. Brooks did individual drills and took reps in one-on-ones against the Ravens during the joint practices last week.

"He's looking really good in everything he's doing. He's moving well," Pederson said. "He's looking good. He's looking powerful. I'm excited about that."

"Thinking Week 1, but at the same time being smart as well," Brooks said. "If I'm physically not ready, then I'm not going to go out there and put myself in a bad position or put my teammates in a bad position. If I'm ready to go and I feel fine, then that's what I'll do."

3. The Eagles have to get to the 53-man roster limit by Saturday at 4 p.m. It's crunch time for the players on the bubble as this week of practice and Thursday's preseason finale at the Jets will present the final opportunities to make a case for a spot on the roster.

"They're tough every year. Tough every year," Pederson said of the looming cuts ahead for the Eagles' front office and coaching staff. "We got to make decisions that affect these players' lives. It's difficult to face them and talk to them. ... Every year it's hard. This will be no different."
