With just one week until the event, the UFC 311 lineup has taken a hit. Light heavyweight veteran Johnny Walker has sustained a “bad injury” that will prevent him from meeting Bogdan Guskov on the Jan. 18 card at Intuit Dome in Inglewood, Calif. ( ESPN+ pay-per-view, ESPNews, ESPN+) The matchup was scheduled to serve as the featured preliminary contest on the UFC’s first numbered event of the year, but Walker (21-9 MMA, 7-6 UFC) said he could not proceed with stepping into the octagon after his injury, and offered an apology to Guskov (16-3 MMA, 2-1 UFC) after announcing his withdrawal on Saturday.
