Bears cornerback Tracy Porter entered the starting lineup in Sunday's win over the Raiders, collecting two tackles and knocking down one pass while seeing 58 snaps.
After missing the first two weeks of the season with a hamstring injury and seeing limited action in the Week 3 blowout loss to the Seahawks, Porter surprisingly displaced Alan Ball from the starting lineup.
He generally fared well in holding upstart rookie Amari Cooper in check, as the No. 4 overall pick reeled in only four of nine targets for 49 yards and a touchdown, with nickel back Sherrick McManis bearing more responsibility on the score than Porter.
With Porter now well removed from the hamstring pull that limited him through much of training camp, it's likely that he'll remain in the starting lineup and function as the Bears' No. 1 corner ahead of Ball and the struggling Kyle Fuller. Look for Porter to match up with the Chiefs' Jeremy Maclin in Week 5.
