Colts QB Luck sitting out with calf not improving

Indianapolis quarterback Andrew Luck’s injured left leg isn’t getting better, so the Colts are sitting down their biggest star.

Luck missed practice in Westfield, Indiana, after telling coaches his strained calf felt worse following the first week of training camp. Coach

Frank Reich announced Luck would be sidelined at least three more days and would miss next week’s preseason opener at Buffalo.

“I feel like something’s going to yank, something’s going to pull trying to change directions aggressively,” Luck said. “That’s something you need to do to play football and I’m not there yet.”

The Colts have been playing it safe with Luck ever since he initially got hurt in the spring.

He missed the team’s offseason workouts, didn’t throw to teammates on the West Coast leading into camp as he usually does and was limited to individual drills and 7-on-7 work last week.

Jacoby Brissett is working with the starters in Luck’s absence. for the first time this offseason. “Hard Knocks” cameras filmed him stretching. They filmed him chatting with teammates.

They filmed him catching a deep touchdown over cornerback Gareon Conley.

And then, halfway into practice, his debut ended.

So, they filmed him walking away. Brown delivered a soft opening before making a planned exit. Gradually, the Raiders are expanding his team activities, as he works past a minor injury that forced his placement on the nonfootball injury list at the start of camp. He won’t be seen again until Thursday; players have an off-day Wednesday.

“That’s just a little preview,” wide receiver J.J. Nelson said. “That’s just a little taste, so just imagine him being in on every play. You know what I’m saying? With (quarterback Derek Carr) back out there and us other guys out there as well, it’s going to be fun. … It’s going to be exciting. I’m looking forward to lighting up the scoreboard.”

Coach Jon Gruden said Brown is “getting close” to full participation.

“Hopefully, after the day off, he will get closer,” he added. “But we need him on the grass. We need him to get going, and he’s champing at the bit. He’s not a real patient guy, and, hopefully, it’ll be sooner than later.”

Brown is not expected to play this preseason.

Peterman power

Gruden cut off a reporter’s question about the position battle between backup quarterbacks Mike Glennon and Nathan Peterman.

He was eager to discuss Peterman, who compiled a horrific stat line the past two seasons with the Buffalo Bills. The Raiders signed him last December with hopes he could compete to be Carr’s primary backup in 2019. So far, he appears off to a favorable start.

“I like these guys,” Gruden said. “This Nate Peterman — not to cut you off — this Nate Peterman is growing on me. He’s athletic. I know he’s had some nightmare performances in the NFL, but when you watch the film, you can see why: It’s not all his fault. But he’s got some talent. He’s got some athleticism. He has some experience. He was an Opening Day starter for the Buffalo Bills last year. I take that very serious.

“And he’s smart. He’s done a good job. He’s been consistent. I think he’s starting to get his confidence back, and we all need that.”

Glennon and Peterman are alternating between second- and thirdteam reps each day.

Notable

Defensive tackle Ronald Ollie, who starred on Netflix series “Last Chance U,” was waived Tuesday. He hadn’t practiced since exiting Saturday midway into camp’s first session. The Raiders also signed defensive tackle Ethan Westbrooks and waived tight end Erik Swoope.

Defensive tackle Gabe Wright suffered an injury late during a red-zone team period. He appeared to favor his right leg while needing assistance to limp off the field.

Rookie seventh-round pick Quinton Bell missed a second straight practice with an injury that is “not as serious as feared,” Gruden said. Bell is expected to be sidelined for another week to 10 days.
