Wayne Brent’s first season is in the books. And it was a disappointing ending.

Jackson State was knocked off by last-seeded Grambling State 84-75 in Tuesday’s first round of the Southwestern Athletic Conference tournament held at the Toyota Center in Houston.

The seventh-seeded Tigres (11-20, 7-10) seemed primed to make run at the finals, with GSU and No. 2 Texas Southern in its bracket, both of whom Jackson State beat twice in the regular season.

But Tuesday’s game underscored the uncertainty of tournament season. For JSU, it was messy, especially considering the bizarre ending with forward Brandon West, who failed to show when JSU was scheduled to leave earlier this week for Houston.

“That was the most disappointing thing with his situation and how it went down the last couple of days, with him missing some practices, missing some meetings and then deciding last minute that he wanted to play — it was just a little too much for me to let go on in this program,” Brent said. “It was a disappointing ending for a team that could have actually made a run, and we needed him to be at his best in order to do it.”

Attempts to reach West were unsuccessful.

Jackson State relied on Treshawn Bolden, Janarius Middleton and Derrell Taylor to make up for West’s absence. Bolden and Taylor combined for 10 rebounds. All had two fouls in the first half, which are what Brent said hurt it the most.

“Having to shuffle guys in and out ... you’re asking them to do something in the Toyota Center where the Houston Rockets play,” Brent said.

JSU trailed throughout the first half. Jeff Stubbs’ foul on Antwan Scott, who finished with 16 points, extended Grambling State’s lead to 10. JSU made three 3-pointers, two from Julysses Nobles, who led all scorers with 28, to cut the lead to 42-39 at halftime. But Grambling (5-23, 4-15) scored off three JSU turnovers in the second half to regain the lead and pick up its first win in the SWAC tournament since 2011.
