SAN LUIS OBISPO – Prior to resuming Big Sky action, the Cal Poly football program completes non-conference play when hosting San Diego on Saturday, Sept. 19. Kickoff on ESPN+ from Mustang Memorial Field is 5 p.m. for Cal Poly (2-1), which seeks its first 3-1 start to a season since 2016. The Mustangs sustained their first setback under first-year head coach Tim Skipper during a 30-20 loss at FBS San Jose State (Sept. 12). San Diego (0-2), meanwhile, opened its year with defeats to No. 6 UC Davis (49-17) and versus No. 24 Idaho State (59-17). With the Mustangs featuring one of the nation’s elite passing threats, three of the Big Sky’s top nine tacklers and steadily climbing the polls, here’s the rundown for Cal Poly’s fourth week of action.  

GRIGSBY CEMENTS PLACE UNDER CENTER

Named Mustang starting quarterback the day of Cal Poly’s 38-34, season-opening victory against Idaho (Aug. 28), Anthony Grigsby, Jr., accounted for all five of Cal Poly’s touchdowns and 319 passing yards versus the Vandals to earn Big Sky Offensive Player of the Week praise. He followed with 204 more passing yards and three touchdown completions against Central Washington (Sept. 5) before hitting San Jose State (Sept. 12) for 249 yards. Emerging as one of the top FCS threats, Grigsby ranks sixth nationally with eight passing touchdowns, 14th with 65 completions and 772 yards, 15th with 21.7 completions per game, 18th with 257.3 passing yards per game and 35th with a 63.7 (65-for-102) percent completion percentage. Responsible for 54 of Cal Poly’s 82 points this season (66 percent), Grigsby needs just two more passing yards to match a 2025 total achieved in six appearances. He’s also thrown just two interceptions in 102 attempts. 

THE GREEN ZONE

The Big Sky’s sixth leading rusher with 72.3 yards per game, junior running back Jaden Green is also third in kickoff returns at 26.7 yards per attempt. Combined, Green – an offseason transfer from Lehigh – is 23rd among FCS performers with 116.3 all-purpose yards per outing. Green’s first Cal Poly touchdown came, ironically, on a six-yard receiving effort at San Jose State (Sept. 12).
