Dec. 14 is the date that's been set for Richard Sherman's appeal of his four-game suspension for alleged use is performance-enhancing drugs, ESPN.com reported Monday. It means Sherman will remain eligible to play in Sunday's home game against Arizona. Brandon Browner, the other Seahawks' cornerback who faces a four-game suspension for suspected use of PED, has not had a date set for his appeal hearing. That means he probably will play in Sunday's game as well. Both cornerbacks tested positive for Adderall, sources told ESPN. The Seahawks (7-5) currently occupy the sixth and final playoff spot in the NFC.
