CHARLOTTE, N.C. -- Panthers running back DeAngelo Williams is in the second year of the five-year, $43.5 million contract yet his future in Carolina has never been more uncertain.

Williams was benched two weeks ago for Jonathan Stewart and has just 13 carries for 37 yards in his last two games.

After Carolina's 23-22 loss to Chicago on Sunday, Williams wrote on his Twitter account: "Well I guess I get to see if all the trade rumors are true or false this (week)! Stay tuned."

On Wednesday he said he's not paying much attention to the trade talks. The deadline for NFL teams to make trades is Thursday at 4 p.m. ET.

"The thought of staying a Panther never really crossed my mind because the thought of leaving never crossed my mind," Williams said. "In my mind, I'm going to continue being a Panther until told otherwise."

Panthers interim general manager Brandon Beane said the team is not shopping Williams, or any other player. Beane said no teams have contacted him this week about Williams, but league sources have told ESPN NFL Insider Adam Schefter that Carolina has been contacted in recent weeks by teams around the league inquiring about the availability of Williams.
