Giants' Fromm: Short-notice start feels like a test after skipping class

New York Giants quarterback Jake Fromm acknowledged the difficulties of potentially starting Sunday versus the Los Angeles Chargers with less than two weeks to absorb the team's offense.

"It's a lot to learn," he told reporters Wednesday. "You're just preparing for a final test where you didn't show up for any of the classes, but it's fun."

Fromm joined the Giants on Dec. 1 with Daniel Jones ailing from a neck injury. He served as the backup to Mike Glennon in Week 13, but the latter entered concussion protocol after losing to the Miami Dolphins, leaving Fromm as the only quarterback remaining.

The Giants are optimistic Glennon will be cleared in time to face the Chargers, but Fromm will draw the nod if the veteran isn't available.

"Learning is what I like to do," Fromm added. "I love football, love scheme. For me, it's really fun."

The Buffalo Bills drafted Fromm with a fifth-round pick in 2020. The Georgia product spent time on the Bills' practice squad but never saw game action.

New York signed Clayton Thorson to the practice squad Tuesday to serve as another layer of quarterback insurance.
