The site tweeted Monday morning that "Scobee tells (Prosser) he's already on his way to Pittsburgh."
The Steelers announced later in the afternoon that they traded a sixth-round pick for Scobee.
The Steelers have already traded a conditional 4th-5th pick in next year's draft for cornerback Brandon Boykin.
The Steelers are in need of a kicker after Shaun Suisham's replacement, Garrett Hartley, injured his hamstring kicking off in Saturday's preseason game at Buffalo. Suisham, of course, is on Injured Reserve with a torn ACL suffered in the Hall of Fame Game.
Scobee, 33, is a 12th-year veteran who's made 81 percent of his career kicks since being drafted out of Louisiana Tech in 2004.
This preseason, Scobee has made both of his field-goal attempts, including a 52-yarder. He was made expendable due to the kicking of rookie Joel Meyers, and because of cost. Meyers has a minimum-wage contract while Scobee is in the last year of a contract that will pay him $3.43 million. The Steelers must take on that salary, although the Jaguars have agreed to pay part of it.
Scobee is a strong-legged kicker who had only 35 percent of his kickoffs returned last season. Suisham, by comparison, had 63 percent of his kickoffs returned.
In a preseason game against the Steelers, Scobee knocked all four of his kickoffs out of the end zone and also kicked a 36-yard field goal.
