"I didn't say anything about the Browns," Darnold told reporters after the Trojans' practice Monday. "I've never said anything bad about [an NFL] team. They know I would never say anything."
Darnold would be one of the top quarterbacks available in the 2018 draft and has been widely projected as a high-first-round draft pick.
His draft availability has been the topic of speculation since earlier this month, when the MMQB's Albert Breer said during a radio interview that Darnold would wait to see whether the Browns had the No. 1 pick before deciding whether to enter the draft.
Darnold, a redshirt sophomore, has passed for 3,462 yards and 24 touchdowns with 12 interceptions this season for the Trojans (10-2), who will play Stanford in the Pac-12 championship game Friday.
The 6-foot-4 Darnold was rated as the fifth-best overall prospect earlier this month on ESPN draft analyst Mel Kiper's latest Big Board.
