The Raiders are hosting veteran pass-rusher Lamarr Houston for a workout today, Ian Rapoport of NFL.com tweets. If Houston signs with the Raiders, it’ll mark a homecoming for Oakland’s former 2010 second-round pick. 
Houston played the best football of his career when he was with the Raiders for his first four NFL seasons. After signing a five-year, $35MM contract with the Bears, he was unable to keep the momentum going thanks to injuries. In his first three campaigns with Chicago, Houston appeared in just 26 of a possible 48 games and made only ten starts.
The Bears cut Houston before the start of the 2017 season, eventually leading him to the injury-marred Texans’ front seven. When Houston was cut by Houston, the Bears brought him back in for the final stretch of the season. In five games with Chicago, he managed four sacks, including two sacks against the Lions on Dec. 16.
There’s reason to believe that Houston can be a solid contributor once again, though perhaps only as a situational pass rusher on limited snaps. If Jon Gruden likes what he sees, it probably won’t cost much for the Raiders to sign him on a one-year deal.
Some guys won’t try to play through the pain but this guy does as best he can. Low risk for Raiders.
