Denver Broncos quarterback Russell Wilson's slow start with the Broncos might be partially due to a shoulder injury.

According to an ESPN report, Wilson suffered the injury during the team's Week 4 game against the Raiders. The shoulder injury was described as a partially torn lat.

The Broncos played the Indianapolis Colts in Week 5 on Thursday night. The next day, Wilson traveled to Los Angeles where he underwent a procedure to help improve discomfort levels in his throwing shoulder, according to reports from the NFL Network.

The procedure was a PRP injection to his shoulder, the NFL Network confirmed.

PRP stands for platelet rich plasma therapy. The procedure typically involves blood being drawn, and then a machine is used to separate "platelets." Those platelets are then re-injected in the body.

The nine-time Pro-Bowl QB has been largely ineffective in his first four games in Denver. He's thrown four touchdowns and three interceptions. The Broncos' offense struggled to gain any real traction in the loss to the Colts on Thursday night.

The 33-year-old quarterback failed to deliver late in the fourth quarter. He threw an interception in the end zone with just two minutes remaining, which gave way to Chase McLaughlin’s game-tying field goal with just seconds left on the clock.
