UConn football coach Bob Diaco said Thursday night on his weekly radio show that quarterback Casey Cochran will not play Saturday against Stony Brook.

Diaco said Cochran sustained an "upper body injury" during the Huskies' 35-10 loss to Brigham Young last Saturday.

Two sources confirmed that Cochran sustained a concussion.

It is unclear the number of games Cochran will miss or whether he will recover in time to start against Boise State on Sept. 13 at Rentschler Field.

Cochran has dealt with concussion issues in the past. One of the sources said Cochran has sustained concussions in youth football, high school football and two others at UConn. He helped lead New London and Masuk to state titles in high school.

Diaco said senior Chandler Whitmer will start for the Huskies and freshman Tim Boyle will move to No. 2 on the depth chart.

Cochran started for the Huskies during last week's loss to BYU, completing 17 of 31 passes for 171 yards.

Diaco said the issue was "brought forth" in the middle of this week.
