Once Dan Koppen was lost to a torn ACL, Lilja had returned from a brief retirement to reconvene with former Colts teammate Peyton Manning in Denver, but his own knee problems appear to have again ended his career.
According to Mike Klis, the Broncos have waived sixth-round tackle Vinston Painter, but hope to get him through waivers and onto their practice squad.
Klis adds that Chris Clark will stick as the main backup tackle, with left guard Zane Beadles the fourth outside option. Louis Vasquez saw some action at right tackle this summer when Orlando Franklin went down with an injury, so he figures to be the fallback beyond Beadles.
More news regarding Denver's moves is trickling in, as the deadline to reach the 53-man roster limit is now four hours away.
Meanwhile, Vic Lombardi reports that RB Jacob Hester and C Steve Vallos have made the squad. That means the team will initially carry five running backs - Ronnie Hillman, Montee Ball, Knowshon Moreno, C.J. Anderson, and Hester - we'll see if Hester sticks once Anderson returns from his MCL sprain.
Ball lost out to undrafted rookie C.J. Anderson, who has made the 53-man roster despite a sprained MCL that's kept him out of action for the past two weeks. Vic Lombardi reports that Anderson is expected to be at full speed in two weeks or sooner.

Hours in advance of the NFL's deadline, the Broncos have gotten down to the 75-man roster limit by placing safety Quinton Carter on irrevocable injured reserve and center J.D. Walton on the regular-season PUP list.
Carter has struggled with health problems since late in the 2011 season, when he injured his left knee against the Patriots. He was placed on IR after just three games in 2012.
In advance of Tuesday's 4pm ET deadline to cut down to 75 players, the Broncos have announced 11 transactions, bringing the roster to 77.
Wide receivers Greg Orton and Quincy McDuffie were waived/injured; Orton suffered a high ankle sprain on the last play of Denver's August 3 scrimmage, while McDuffie had been slowed by a hamstring problem.
The Browns had agreed to trade DE Brian Sanford to the Seahawks in exchange for guard John Moffitt on Monday, but health concerns surrounding the former third-rounder convinced Cleveland to cancel the deal on Tuesday.
Seattle wasted no time finding a new trade partner, and has instead sent Moffitt to Denver in exchange for DT Sealver Siliga.
Superstar linebacker Von Miller has been suspended six games without pay by the NFL for having violated the league's substance abuse policy.
As this was a negotiated suspension, Miller will not appeal.
He will miss the first six games of Denver's regular season: versus Baltimore, at the Giants, versus Oakland and Philly, at Dallas, and against Jacksonville.
During his suspension, Von may not practice with the team or attend games, but he may participate in team meetings and work out at Dove Valley.
Facing a shortage a linebacker due to the looming suspension of Von Miller and wrist surgery for Stewart Bradley, the Broncos have reportedly signed 35-year-old Paris Lenon to shore up the group.
In 11 seasons with the Packers, Lions, Rams, and Cardinals, Lenon has started 122 of the 175 games in which he's appeared, including 48 consecutive starts with Arizona over the past three years.
The Broncos have essentially converted the $1.05M injury settlement Chris Kuper would have been due into a guaranteed salary for 2013. The reworked deal saves Denver $3.45M in cash and against the cap.
According to Mike Klis, Kuper can earn an additional $1.7M in incentives, while his 2014 and 2015 (nonguaranteed) salaries remain unchanged.
This is a win for the Broncos; as for Kuper, he had hardly any choice in the matter.
