He has been slotted as an inside linebacker by coach John Fox but whether Shea McClellin is playing that position in Chicago beyond this season is yet to be determined.
Bears GM Ryan Pace announced that the team won't pick up the fifth year club option on McClellin's rookie contract.

The option would have committed the Bears to a base salary for McClellin of more than $7.7 million for 2016.
The Bears under former GM Phil Emery credited McClellin with a career-best 84 tackles last season, fourth-highest among Bears. NFL stats, typically lower than team totals, credited him with 36.

McClellin, the 19th pick of the 2012 draft, is one of only a handful of 2012 No. 1's not to have the fifth-year option picked up yet. The San Diego Chargers picked up the option on rush linebacker Melvin Ingram, taken No. 18. The Tennessee Titans picked up their option for wide receiver Kendall Wright, selected No. 20.
