Lohner is expected to miss two weeks after undergoing a lower-body procedure, Mike Klis of 9News Denver reports.
Klis adds that Lohner's procedure was a routine cleanup and that he'll be fully ready for training camp. The second-year tight end spent his rookie season on the Broncos' practice squad and signed a reserve/future contract with the team in January. Lohner was lauded by Denver coach Sean Payton as a standout performer while participating in rookie minicamp this May, and he'll look to impress again when he's healthy this offseason.
