Tim Jennings undergoes arthroscopic knee surgery

Chicago Bears cornerback Tim Jennings posted a status and picture on Twitter of himself sitting in a wheelchair on Friday alluding to him undergoing some type of surgical procedure, before later deleting the status and picture.

But according to a source, Jennings underwent arthroscopic knee surgery. The source, who declined to say which knee Jennings had scoped, called the procedure a “simple clean out."

Jennings isn’t expected to miss time in the club’s offseason conditioning program as most arthroscopic knee surgeries require just a two- to three-week recovery period.

Jennings is coming off a subpar 2014 campaign in which he contributed 66 tackles in 16 starts with eight pass breakups and one forced fumble. The recent arthroscopic surgery indicates Jennings played through some knee pain throughout the season.

The team signed Jennings to a four-year, $22.4 million extension last January, when former general manager Phil Emery said the deal was "rewarding excellence" for a veteran who took on the responsibilities in 2013 as a No. 1 cornerback after Charles Tillman suffered a season-ending injury.

Jennings' deal was worth $11.8 million guaranteed and included a $3 million signing bonus.

Jennings earned trips to the Pro Bowl in 2012 and 2013, and picked off 13 passes since the start of the 2012 season, which ranks No. 2 in the NFL behind Seattle's Richard Sherman. Jennings is also tied for fourth in the NFL since the start of 2012 in interception returns for touchdown (three).

At the end of this past season, Jennings placed the blame on the players and not the coaches for the Bears' 5-11 record, and said he hoped the next head coach would help the defense to regain its identity.

A nine-year veteran, Jennings has started in 95 of 131 games played with the Indianapolis Colts (2006-09) and Bears.
