Via Vic Lombardi
Just to add to my report. Broncos LB Brandon Marshall did indeed have surgery on his foot last month. But he should be ready come camp.

Vic appeared on the fan morning show and the speculation is that Marshall has some sort Lisfranc injury. The Broncos have not released anything official.
Lisfranc has been a long-standing enemy of the Broncos. It has bitten a player seemingly each season for several consecutive season. This injury is probably what expedited the end of Champ Bailey's career in the NFL.
