The news comes on the same day Watson was named NFL Offensive Player of the Month, NFL Rookie of the Month, and NFL Offensive Player of the Week.
Watson finished third and second in the Heisman Trophy voting for the 2015 and 2016 seasons respectively. But coach Bill O'Brien insisted he back up Tom Savage. Watson was not able to rally them to victory, but he won his next start and has been off to the races since. Since then, he's turned a team known for defense into one with a high-flying offense.
Watson completed 77 of 124 passes for 1,171 yards with 16 touchdowns and five interceptions in four games last month.More news: Hazard refuses to give up on Premier League title
