According to Reggie Wayne, he was fined $5,500 because his pants weren't long enough as they didn't cover his knees (via Indy Star).— NFL on ESPN (@ESPNNFL) September 28, 2014
Per the NFL's Rule and Regulations:
Pants must be worn over the entire knee area; pants shortened or rolled up to meet the stockings above the knee are prohibited. No part of the pants may be cut away unless an appropriate gusset or other device is used to replace the removed material. All pants must carry a small NFL Equipment logo on the front left groin area of the pants, midway between the fly opening and side seam, and 1/2- inch below the belt.
In 2012, Wayne violated the NFL's uniform policy when he wore orange gloves and an orange mouthpiece in support of Indianapolis head coach Chuck Pagano being diagnosed with acute promyelocytic leukemia. The color signifies awareness for the disease.
Wayne, a six-time Pro Bowler, has played all 14 seasons with the Colts. He led the league in receiving yards in 2007. On Sunday, Wayne joined Peyton Manning and Johnny Unitas as the only players to play in more than 200 games with the franchise.
