Kansas City Chiefs linebacker Justin Houston appears unlikely to play this week against the New England Patriots, while guard Laurent Duvernay-Tardif’s broken leg is worse than initially believed.”I think it’ll be a stretch for Justin,” head coach Andy Reid told reporters Wednesday of Houston’s Week 6 availability. NFL Network reported earlier this week that Houston could miss “a few weeks” after pulling his hamstring in Sunday’s win over the Jacksonville Jaguars.Reid also revealed that Duvernay-Tardif, who was placed on injured reserve Tuesday but was expected to return later this season, could now miss the rest of 2018. Additional testing revealed that Duvernay-Tardif has a Maisonneuve fracture — an external rotation of the ankle that damages ligaments and creates a spiral fracture up the fibula — and needs surgery.Chiefs VP of sports medicine and performance Rick Burkholder said Duvernay-Tardif will have surgery in Green Bay on Monday, after which the timeline for his return will become clearer. Five-year veteran Jordan Devey (37 career games, 15 starts) is expected to start at right guard moving forward, beginning against his former team, the Patriots, this week.Meanwhile, Reid said safety Eric Berry, who hasn’t played or practiced since before the preseason slate began, remains “day-to-day” as he again sat out Wednesday. NFL Network reported last week that Berry has a Haglund’s deformity in his Achilles tendon, a painful issue in which a bone spur digs into the tendon. It remains unclear when Berry might be able to return.Burkholder added that safety Armani Watts, who was also placed on IR on Tuesday, will have core muscle surgery Thursday.
