Seattle Seahawks cornerback Richard Sherman is arguing that his urine specimen that led to a four-game suspension for performance-enhancing drugs was contaminated while being collected for testing, according to ESPN's Adam Schefter.
Sherman is currently appealing his suspension and the contamination argument is a major part of Sherman's appeal. According to Schefter, Sherman claims the cup containing his urine specimen was "leaking, prompting the collector to place a second cup underneath it to capture any leakage."
If Sherman's contamination argument holds up and it is ruled that the second cup's seal was broken, Sherman could win his appeal and not miss any games due to suspension.
Sherman is a major cog in the Seahawks' second-ranked defense and will be on the field to face the NFC West rival San Francisco 49ers on Sunday Night Football. The Seahawks are 9-5 this season and still in the hunt for the NFC West crown if they can defeat the current division-leading 49ers.
