Plummer questionable against Steelers

DENVER -- Broncos quarterback Jake Plummer isn't sure if he'll play Sunday after aggravating an injury to his throwing shoulder against Kansas City.

Plummer didn't throw in practice Wednesday and a decision on his status for Sunday's game against Pittsburgh likely won't come until Friday. He is expected to test his shoulder Thursday and increase his throws on Friday.

"We'll keep our fingers crossed and see what he can do tomorrow," Broncos coach Mike Shanahan said. "If he doesn't get the proper reps and we don't feel like he's ready to go, then the big decision is, is he the second guy or the third guy?"

Plummer partially separated his shoulder while diving for a first down in the first half against San Diego on Sept. 14. He aggravated the injury last weekend against the Chiefs when he was knocked to the ground on a pass that hit center Tom Nalen.

Plummer said he feels about the same as he did following the Chargers' game, but the soreness is in a different area.

"I landed on it a little differently," Plummer said. "I was thrown into it on the ground so I think there's more tenderness on it, whereas in San Diego I really didn't land on it quite as hard."

Plummer bounced back from the original injury to throw two touchdown passes the next week against Oakland, but he also had an extra day of recovery since that game was on a Monday night.

"It's still tender, but it is still early in the week," Plummer said. "I'm not going to say I can't play or that I can for sure, but we'll see how it keeps responding. Probably the same routine we did heading up to the Oakland game."
