Portis ran without any problems during drills Wednesday and will
see if he can handle being hit in a workout Thursday.
"There was no setback, but until he actually goes through a
practice where there's contact it's really hard to know for sure,"
Broncos coach Mike Shanahan said. "We'll definitely get some
contact tomorrow for him to play on Sunday. We'll see if he can
take some shots and hold onto the football."
Portis bruised his chest Sept. 14 against San Diego when
Chargers safety Kwamie Lassiter hit him under the pads. He returned
the next week against Oakland, but aggravated the injury after
landing on his shoulder in the first half.
Portis took just two snaps in the second half against the
Raiders and sat out last week's game against Detroit.
The Broncos also are holding out hope that center Tom Nalen will
be able to return from a sprained ankle suffered late against the
Lions on Sunday.
Nalen was walking better Wednesday, but still had a limp and
didn't practice. He will likely be held out on Thursday before
testing it Friday.
