ENGLEWOOD, Colo. -- Broncos offensive guard Ben Hamilton has been placed on injured reserve with post-concussion symptoms, making him ineligible for the remainder of the season.
The seven-year veteran has missed all three games this season, breaking his streak of 5,407 consecutive snaps that began when he became the Broncos' starting left guard in 2002.
"I talked to Ben Hamilton and his wife for a while," coach Mike Shanahan said. "We came to the conclusion Ben is going to go on IR this season. We thought it was in his best interest."
Hamilton was injured on what he termed a "routine hit" early in training camp when he banged helmets with a teammate. He tried to come back but kept getting nauseated whenever he did cardiovascular work. Hamilton has been seeing specialists in Pittsburgh for several weeks and had been ordered to stay home in hopes that would aid his recovery.
"He really didn't want it, but he's been struggling here for the last six or seven weeks," Shanahan said. "And his condition is a big question mark, if he was going to be ready for the remainder of the season.
"We thought it would be in his best interest not to try to come back."
The Broncos also released wide receiver Brian Clark. They filled the roster spots by promoting wide receiver Glenn Martinez and safety Steve Cargile from their practice squad on Saturday.
