Smyrna-alum Will Knight rushed for a touchdown before Justis Henley's interception locked up Delaware's 44-36 victory at Rhode Island for the Blue Hens' 700th program victory.
Delaware's offense sputtered in the first half, settling for just a missed field goal as they went into the locker room down 13-0, thanks to 2 goal-line stands by their defense that URI was forced to settle for field goals with.
URI's only first-half touchdown came from Delcastle's Ahmere Dorsey, who powered in from 11 yards away on a direct snap.
The Blue Hens would take the lead in the 3rd quarter when Pat Kehoe hit William Penn's Chichi Amachi for a 66 yard score, and then tight end Bryce De Maille was left open for a 21 yard touchdown for a 14-13 lead.
Kehoe's 3rd second-half touchdown went to Owen Tyler, but URI tied the game with a field goal with :19 left to force overtime.
The teams traded touchdowns in each of the first two overtimes, with Delaware getting touchdowns from Andre Robinson and De Maille, while Dorsey scored the second of URI's touchdowns.
In the opening part of the third overtime, Kehoe hit Knight out of the backfield for Kehoe's 5th touchdown pass after halftime, and then Delaware's defense held in the second half to claim the victory.
Kehoe finished 26-for-38 with 282 yards, 5 touchdowns, and 3 interceptions.
Amachi led Delaware with 73 receiving yards on 3 catches, as 8 different receivers caught the 27 total completions between Kehoe and Nolan Henderson.
Andre Robinson led Delaware with 20 carries for 111 yards and a touchdown. DeJoun Lee gained 54 yards before leaving with an injury. Henderson also rushed for 22 yards.
Dorsey caught 6 passes for 99 yards for URI, and added the 11-yard touchdown run, 3 kickoff returns for 66 yards, and 3 punt returns for 23 yards.
Delaware (2-0, 1-0 CAA) returns home to face No. 1 North Dakota State Saturday at 1 p.m.
