ENGLEWOOD, Colo. (AP) Brandon Marshall is back on the football field, trying to replicate last year's breakout season despite two screws in his right foot and a heavy heart.
Marshall led the Broncos with 111 tackles last year despite being hobbled down the stretch by a right foot injury that required offseason surgery.
Because he didn't have the operation until March, he'll have to play the whole season before surgeons can remove hardware in his right foot, meaning he'll have to manage some pain along the way.
He said his foot feels fine so far, but the pain he's dealing with now is the grief over his grandfather's death.
Little Roy Williams, 88, died on July 7 after contracting pneumonia following surgery, Marshall said.
''He had an uncle named Big,'' Marshall said, ''so they named him Little.''
Marshall's mother, Barbara, is the youngest of a dozen children: ''My mom, she's a daddy's girl, so we were always at his house,'' Marshall said. ''He was just like a father to me.''
After attending the funeral, Marshall retreated to Miami, where he got a tattoo on his left pectoral in honor of his grandfather, who was a carpenter.
It depicts a hammer and nails, one of them ''piercing'' his chest and drawing a trickle of ''blood.''
''He's on my chest,'' Marshall said.
Marshall's offseason was cut short because the Broncos wanted him and fellow inside linebacker Danny Trevathan (left kneecap) to report with the rookies Monday instead of with the veterans on Thursday.
''At first I didn't want to come in early but it honestly helped me,'' said Marshall, who missed all of the team's offseason field work.
Trevathan, the Broncos' top tackler in 2013, worked his way onto the field in June but spent most of the offseason practices with Marshall on the sideline.
The middle linebackers are the fulcrum of Wade Philips' 3-4 defensive scheme, and there's major questions surrounding Marshall and Trevathan as they return from their injuries.
Not in their minds, though.
''Danny and I are very confident. We believe in each other. We believe in ourselves,'' Marshall said.
Trevathan said he and Marshall worked diligently all offseason in the classroom, weight room and training room.
''A lot of people had doubts about us and what we could do because of our injuries. It was just positive stuff with me and him,'' Trevathan said. ''Brandon came in with the right attitude. I came in with the right attitude, and we've been attacking these practices day by day.
''We've been smart and taking care of each other. That's going to help us be one of the best duos in the league.''
Safety T.J. Ward said he's glad to see Marshall and Trevathan back on the field, even if it's just cameos.
''Man, a tremendous boost just seeing them out there,'' Trevathan said. ''They're not going full-speed, doing everything we're doing right now. But walkthroughs and 7-on-7s, just having them two down there has been great. Just seeing them down there is kind of another level of comfort.''
Anguish or not, Marshall plans to approach this summer's camp with the same dogged determination that helped him have a breakout season last year after bouncing around the practice squads in Jacksonville and Denver.
''I can't let myself get comfortable and say, `You know what, I've got a body of work, I'm good.' No, I can't do that,'' Marshall said. ''I've got to treat it just like every other year because this is the most competitive sport in the world, man. Everybody's out for your job. And I want to be the best, so why would I let myself get comfortable?''
