Raiders put right tackle Donald Penn on IR with groin injury

ALAMEDA, Calif. -- The Oakland Raiders placed veteran right tackle Donald Penn on injured reserve Wednesday, three days after he left the team's 45-42 overtime victory in the third quarter with a groin injury.

Penn, 35, left the previous week's game at Miami with concussion-like symptoms.

"Hopefully we'll get him back late in the season," said Raiders coach Jon Gruden.

Teams can bring back as many as two players off IR, and defensive tackle Justin Ellis is also a candidate.

While the Raiders signed offensive tackle Ian Silberman off the Tennessee Titans' practice squad, Gruden said third-round draft pick Brandon Parker would start at right tackle at the Los Angeles Chargers this weekend.Silberman was on Oakland's active roster last December and started two preseason games at right tackle this summer before making the team's initial 53-man roster and being waived a day later.

With first-rounder Kolton Miller at left tackle, it will be the first time the Raiders start two rookies at the offensive tackle positions since at least the 1970 AFL-NFL merger, per the Elias Sports Bureau.

ESPN Stats & Information found that since 2007, five different teams have started rookie offensive tackles in a game, and the Raiders would be the third team to start rookie tackles picked within the first three rounds:

• Arizona Cardinals (2012): Bobby Massie (fourth round) and Nate Potter (seventh round) for six games, Weeks 11-16.



• Kansas City Chiefs (2012): Jeff Allen (second round) and Donald Stephenson (third round) in Week 17.


• New York Giants (2015): Ereck Flowers (first round) and Bobby Hart (seventh round) in Week 13.


• Jacksonville Jaguars (2009): Eugene Monroe (first round) and Eben Britton (second round) started 13 games together that season.


• Baltimore Ravens (2007): Marshal Yanda (third round) and Jared Gaither (fifth round) for two games, Weeks 6-7.


• Ravens (2016): Ronnie Stanley (first round) and Alex Lewis (fourth round) in Week 1.

Parker, who missed time in training camp with an ankle injury, said earlier this week that Penn gave him "pointers" on the sideline after he replaced him against the Browns and former No. 1 overall pick Myles Garrett.

"That man's strong," Parker said of Garrett. "I actually went on the bench and asked Kolton, 'Why didn't you tell me he was that strong?' He said, 'You didn't see me get bull-rushed all game?' Yeah, he's strong."

In Penn, the Raiders are losing the services of a three-time Pro Bowler who entered the NFL in 2004 as an undrafted rookie out of Utah State and had a streak of 170 consecutive starts end last year with a Lisfranc injury to his right foot in Week 15.

Penn, who held out of training camp in 2017 and received a contract extension, restructured his deal in camp this year, as his $3 million base salary for 2018 became fully guaranteed. He moved from left to right tackle this season.

"Obviously, I love Donald, so I'll miss him for however long that is," said Raiders quarterback Derek Carr. "With Brandon, I think everyone knows how we feel about him around here -- he's really good. I'm sure he had a couple plays as a rookie that he'd want back, but you live with that. He's tough, he's very intelligent, so crazy looks and things like that aren't going to mess with him. Which is good. He's one of the smartest rookies I've ever been around."

Miller, the No. 15 overall pick, has played all 288 snaps for Oakland's offense thus far for an offensive line that has allowed pressure on 24 percent of dropbacks, the seventh-lowest rate in the NFL, per ESPN Stats & Information.

"We know how Kolton is -- Kolton's awesome, he's a stud," Carr added. "You don't feel like you have two rookies because they're so talented, but at the end of the day, they are. It's something we've got to do a good job of just helping those guys out."
