LAS VEGAS – UFC 279 is still a few days away, but Jake Shields already got a dose of Khamzat Chimaev . The former Strikeforce champion and teammate of Nate Diaz said he was part of a run-in with Chimaev on Monnday while he was helping UFC middleweight Paulo Costa work on his grappling. Shields told MMA Junkie Radio that Chimaev interrupted the grappling session between him and Costa at the UFC Performance Institute in Las Vegas, which he wasn’t happy about.
