PITTSBURGH -- One of the interesting things to watch early in Thursday’s game between the Pittsburgh Steelers and Tennessee Titans will be the performance of backup linebacker Keyaron Fox.
Fox, 27, is replacing inside linebacker Lawrence Timmons (ankle) in the starting lineup of a huge season opener for both teams.
This is the fifth career start for Fox and his first in Pittsburgh. He had a good preseason for the Steelers, but primarily a special-teams player, Fox will need to step up his game even further against the run-heavy Titans.
Pittsburgh released veteran linebacker Larry Foote this offseason to get Timmons into the starting lineup. But that also hurt Pittsburgh’s depth, leaving Fox with some big shoes to fill.
