BOULDER, Colo. (AP) — Colorado didn't think they'd win in a walk.
They didn't think they'd lose to a walk-on, either.
Edgar Castaneda's 30-yard field goal as time expired gave Sacramento State a stunning 30-28 win over Colorado on Saturday — and earned him a scholarship in the process.
The Buffaloes (0-2) simply earned another hard-luck loss to an FCS-level opponent. They also lost to Montana State at home in 2006 and edged Eastern Washington by a touchdown two years later.
"I did not come into this game feeling like we were going to dominate," Colorado coach Jon Embree said. "I came into this game thinking it was going to be a football game that we were going to have to fight and win.
"It doesn't matter who it is; it's tough to lose, period. It's never fun or easy when you lose."
For the second straight game, the Buffaloes let a fourth-quarter lead slip away after in-state rival Colorado State rallied to beat them last week.
Colorado seemed in control, with possession and leading 28-27 with 4:42 left. But freshman fullback Christian Powell, who ran for 147 yards and three touchdowns, was stuffed on third-and-3, forcing a punt.
The Hornets got the ball at their own 15 with 2:26 left and marched downfield for the game-winner by Castaneda, after which wide receiver Austin Dotson did a series of backflips as his teammates swarmed the field.
Castaneda, a walk-on, joined the Hornets after helping City College of San Francisco win the junior college national championship last season, but he was paying his own way until Saturday, when his first game-winner at any level earned him not only a hug from coach Marshall Sperbeck, but also an education.
Sperbeck made the announcement during his postgame speech in the Hornets' locker room.
The Hornets (1-1) also left Boulder with a $460,000 paycheck following a stunning victory at a Pac-12 stadium for the second straight season. They upset Oregon State 29-28 in overtime in last year's opener.
