Now that both star defenders have lost the rest of the 2017 season due to injuries sustained in Week 5, general manager Rick Smith is bringing in a pair of established veterans to bolster his suddenly shallow pass rushing corps.
Although both players have spent the bulk of their careers as above-average starters, they were still languishing on the open market due to knee injuries that have arisen over the past few years.
After starting 60 of 64 games over four years in Oakland, Houston landed a five-year, $35 million contract from the Bears in 2014. Eight games into his Chicago career, he suffered a torn ACL. Just two games into the 2016 season, Houston tore the other ACL in his other knee. When Houston came down with knee soreness late this summer, the Bears released him with an injury settlement.
