Boone, NC (Sports Network) - The Illinois State football players must be thrilled to be on the road during the FCS playoffs.

The Redbirds have yet to lose in six road games this season, and Saturday's 38-37 overtime victory at Appalachian State in the second round was their biggest yet.

Senior quarterback Matt Brown threw for five touchdowns and 322 yards, and the Redbirds blocked an extra point to end overtime when Appalachian State was trying to tie the game again.

Illinois State (9-3), in the playoffs for the first time since 2006, will play the Wagner-Eastern Washington winner in the national quarterfinals next weekend.

Brown's 25-yard touchdown pass to James O'Shaughnessy in overtime gave Illinois State a 38-31 lead. Appalachian State answered with Jamal Jackson's 4-yard touchdown pass to Andrew Peacock to make it 38-37. But Sam Martin's extra point attempt was then blocked.

Brown, the Missouri Valley Football Conference's offensive player of the year, completed 20-of-32 pass attempts. Having set seven school records and four conference records this season, he went over 10,000 career passing yards, increasing his total to 10,219.

Tyrone Walker caught 10 passes for 176 yards and two touchdowns. O'Shaughnessy also caught two touchdowns.

Appalachian State forced overtime when Peacock's 10-yard touchdown pass to Drew Bailey with 3:31 left tied the game at 31-31.

Jackson was 33-of-45 for 373 yards and two touchdowns with one interception.

His favorite receiver, Sean Price, ended his outstanding redshirt freshman by catching 13 passes for 167 yards. He broke the FCS freshman records for receptions and receiving yards in a season with 71 and 1,196, respectively.

The loss ended Appalachian State's season with an 8-4 record. The Mountaineers were making their eighth straight playoff appearance, but it was their third straight defeat at home in the postseason.

It was the first meeting between the two programs.

Old Dominion 63, Coastal Carolina 35

Norfolk, VA (Sports Network) - Coastal Carolina did its best to try to match touchdowns with the No. 1-ranked offense in the FCS.

And then the Taylor Heinicke onslaught only worsened for the Chanticleers.

Old Dominion's sensational sophomore quarterback threw for three straight touchdowns in just over a five-minute span of the second half and he went on to pass for 497 yards and six touchdowns in the Monarchs' 63-35 victory over Coastal in the second round of the playoffs Saturday.

Heinicke completed 32 of his 44 pass attempts and didn't throw an interception, propelling fourth-seeded Old Dominion (11-1) into next weekend's national quarterfinals, where they will host fifth-seeded Georgia Southern (9-3).

Georgia Southern eliminated ODU from last year's playoffs, 55-48.

Coastal (8-5) tied the game at 35-35 on Travis Small's 18-yard touchdown run with 2:53 left in the third quarter before Heinicke then helped ODU pull away to its sixth straight win.

He led the Monarchs on a quick touchdown drive, completing four passes for 72 yards and capping it with a 6-yard scoring pass to Larry Pinkard with 1:01 left in the quarter.

After Coastal went three-and-out on its next series, Heinicke opened the fourth quarter with a 73-yard touchdown pass to Pinkard, extending ODU's lead to 49-35.

Heinicke then threw a 13-yard touchdown pass to Nick Mayers to push ODU's lead to 56-35 with 10:52 left in the game.

The Monarchs then scored again on their next possession with Colby Goodwyn's 5-yard touchdown run.

Heinicke has thrown for 4,655 yards and 41 touchdowns this season.

Pinkard caught six passes for 154 yards and three touchdowns, while Mayers finished with six receptions for 103 yards and one touchdown. Two of Blair Roberts' four receptions went for touchdowns.

ODU finished with 694 yards of offense. The Monarchs, from CAA Football, entered Saturday's action ranked No. 1 in total offense and No. 2 in scoring offense in the FCS.

For Coastal, which was coming off a first-round win at Bethune-Cookman, Aramis Hillary was 21-of-39 for 352 yards and three touchdowns with two interceptions. Matt Hazel caught nine passes for 155 yards and two touchdowns.
