WATCH: Richard Sherman takes jab at NFL for 'random' drug testing

San Francisco cornerback Richard Sherman called out the NFL with a touch of humor on Thursday after learning he was “randomly” selected for both a PED test and a blood test two weeks in a row.

The outspoken corner sent a pair of telling tweets from Miami, the site of Super Bowl LIV, as he and the 49ers get ready to face the Kansas City Chiefs on Sunday:

Sherman is still at the top of his game at 31 years old, making the NFL’s 2019 All-Pro team and receiving another Pro Bowl nod just a few weeks ago. He’s logged five interceptions this season, including one in both of the Niners’ playoff games leading up to Super Bowl Sunday.
