Pulver took the fight to the floor late in the first, only to have opponent Brian Davidson take his back for the rear-naked choke at four minutes and 14 seconds.
Quick results of all the Titan FC 18 fights after the jump.
In the co-headliner, UFC veteran and three-time NCAA wrestling champion Jake Rosholt suffered a tough loss when he was disqualified in the third round against John Ott due to an illegal knee to a grounded opponent. Up until that point, Rosholt was winning the fight and arguably should have already won by TKO due to the amount of damage Ott received.
The 28-year-old Rosholt was joined on the card by his younger brother Jared, who improved to 3-0 with a first-round TKO victory.
