Raiders All-Pro punter Shane Lechler had minor knee surgery prior to the team's training camp, head coach Dennis Allen confirmed Wednesday.
A scope to clean out his left knee forced Lechler to miss the Raiders' preseason opener against the Dallas Cowboys on Monday. He may not play in their Friday night game against Arizona, but Allen is hopeful his punter will see action this preseason.
Lechler, who has missed just two games since his rookie season in 2000, said he is certain he'll be ready to punt by the regular season, leaving the rest of the decisions up to the coaching and medical staffs.
Lechler has been on the Raiders' Non-Football Injury list with what was described as a left knee ailment.
"He had a scope," Allen acknowledged Wednesday after guessing on Aug. 6 that Lechler was a week away from returning to the field.
Lechler, 36, is a seven-time Pro Bowler and six-time All-Pro entering his 13th NFL season, all of which have come with Oakland.
Lechler swings a powerful leg. He has led the league in average yards per punt five times and he achieved an average greater than 50 for the second time in his career last season.
Rookie Marquette King is handling the punting in Lechler's absence. He averaged 40.2 yards in Monday's loss, pinning two of his five kicks inside the 20-yard line.
Raiders Pro Bowl left guard Kelechi Osemele, running back Taiwan Jones and safety Brynden Trawick are currently enjoying their offseason in New Zealand.
But a few videos they posted going white-water rafting and bungee jumping left head coach Jack Del Rio a bit anxious.
"Anxiety level went up a bit thinking of my BIG pro bowl LG on the rapids!!" Del Rio tweeted Monday. "Can't leave out Brynden or Taiwan either ... have fun and be safe"
Osemele has posted a handful of photos and videos from the trip, including one of a raft capsizing with the caption: "It got real out there!!! Category 4 Rapids #NewZealand." Another showed the 6-foot-5, 333-pounder doing a backflip off a bungee platform with the caption: "Just did a backflip off the highest swing in the WORLD!!!!!!! Crazy!!! #LivingLife"
Trent Richardson is reportedly in some trouble.
Richardson was arrested on Thursday night for domestic violence, according to TMZ Sports.
The former running back was taken into custody on a third degree charge, the report states, with bail being set for $1,000.
The arrest was made in Hoover, Alabama.
The Browns selected Richardson with the third overall pick in the 2012 draft.
He was traded to the Colts in 2013 and played for Indianapolis in 2014.
He signed with the Raiders in 2015 and appeared in three exhibition games, but did not make the team.
The 26-year old was cut by the Ravens last August.
