Manning threw passes for "about a half hour" Wednesday morning inside the Pat Bowlen Fieldhouse, Head Coach Gary Kubiak said.
"He went through some drill work and stuff," Kubiak added. "We're going day-to-day with that, and we'll see how he comes out of each day, but yes, there was some [on-]field work done."
Kubiak said that he was not sure whether a rest day would follow Manning's throwing session. The 18-year veteran quarterback took a rest day Tuesday after working on rehabilitation work from Saturday through Monday.
"We'll see how he comes out of each day, so we'll just take it day by day," Kubiak said.
