This will be Glover Teixeira's second UFC light heavyweight title shot

Glover Teixeira last fought for the UFC light heavyweight championship way back in April 2014 at UFC 172. He took on titleholder Jon Jones in the pay-per-view headliner.

'Bones' won the bout via unanimous decision. It has taken Teixeira more than seven years to secure another title shot.

The No.1-ranked contender has never been submitted in his career and has gone to the judges' scorecards just nine times in his 39 professional fights.

Meanwhile, Jan Blachowicz claimed the light heavyweight belt at UFC 253 last September. He defeated Dominick Reyes to win the title, which was vacated by Jones earlier in the year.

Blachowicz has made one successful title defense so far. It came against UFC middleweight champion Israel Adesanya, who had moved up a weight class in an attempt to become a two-division titleholder.

The 38-year-old Warsaw resident came out on top against 'The Last Stylebender' via unanimous decision at UFC 259 in March this year. He'll be looking to record his second successful defense at UFC 267 on Saturday.
