The San Francisco 49ers were among several NFL teams on hand to watch quarterback Chad Kanoff at Princeton's pro day on Friday, according to Tony Pauline of Draft Analyst.

Pauline, who says that Kanoff did not disappoint during the workout, wrote the following:

"The big-armed passer measured in at 6-foot-4 and 219 pounds, timed 4.90 in the 40 and posted a vertical jump of 32.5 inches. His hands measured 10-1/4 inches, a big number for a quarterback. Kanoff threw 55 passes; all had excellent velocity, and all were on the money. The Giants, Arizona Cardinals, San Francisco 49ers and Indianapolis Colts have all shown a lot of interest in Kanoff and were in attendance today. The Cardinals intended to have multiple people on hand, but the weather prevented some from attending."

Kanoff completed 73.2 percent of his passes for 3,474 yards with 29 touchdowns and nine interceptions for the Tigers in 2017, according to Fox Sports.
