(CBS) With top receiver Alshon Jeffery suspended for four games, the Bears will need help in the passing game. Look no further than receiver Marquess Wilson, who has been officially activated from the physically-unable-to-perform list.

Wilson suffered a broken foot during the offseason program. He was placed on PUP at the beginning of the season and began practicing last Monday, with the Bears coming out of their bye week. Wilson is now eligible to play and should see plenty of opportunities in the passing game.

On Monday, the NFL announced that Jeffery had been suspended four games for violating its policy on performance-enhancing drugs. In a statement, Jeffery admitted to his mistake.

“As a professional athlete, I have been careful about what I put in my body,” Jeffery wrote on Twitter. “I took a recommended supplement to combat inflammation. Unfortunately this supplement contained an ingredient that was on the NFL’s banned substance list. I take full responsibility and I’m deeply upset with myself for not doing the proper research on this supplement.”

A seventh-round pick in 2013, Wilson has played in just 28 career games, recording 47 catches and two touchdowns. He has yet to play a full season due to several injuries.

The Bears also made several other roster moves Tuesday. They placed guard Kyle Long and nose tackle Will Sutton on injured reserve with ankle injuries, effectively ending their seasons. Veteran defensive lineman C.J. Wilson again signed with the team. Center Cornelius Edison has been promoted from the practice squad to the active roster.

Additionally, the Bears signed quarterback Josh Woodrum to the practice squad. He’s now third in line behind Jay Cutler and Matt Barkley.

The Bears return to work Wednesday and begin their preparation for their Week 11 contest with the Giants.
